Maple Leafs Want to Trade Recently Signed Forward

Maple Leafs Want to Trade Recently Signed Forward

The Toronto Maple Leafs reached an agreement on a contract extension with 23-year-old forward Nick Robertson, avoiding an arbitration case. Robertson signed a one-year deal with the Maple Leafs, earning him $1.825 million against the salary cap. While Robertson signed an extension with the Maple Leafs, it’s not likely he sticks around in Toronto for too much longer. According to Elliotte Friedman on the 32 Thought Podcast, the Maple Leafs have more players on their roster than they’d like and Robertson is the low hanging fruit in the lineup. “The Maple Leafs have to clear some bodies there,” Friedman said. “There’s a lot of them” Robertson has been connected to teams like the Pittsburgh Penguins and Columbus Blue Jackets, but it’ll be up to the Maple Leafs to decide if/where they want to send him. “I definitely think the Maple Leafs have work to do here,” I don’t know what their timeline is, but nobody expects them not to do things before puck drops, that’s for sure.” For a number of years, Robertson was one of the top prospects in the Maple Leafs system but hasn’t been able to find regular time in the NHL lineup. Whether through his own development as a professional hockey player or the Maple Leafs not having room in the lineup, Robertson hasn’t seen much NHL time in his career. Robertson appeared in a career-high 69 games during the 2024-25 season, recording 15 goals and seven assists for 22 total points. Usually relegated to the bottom six of the Maple Leafs’ lineup, Robertson has played in 156 career games with 32 goals and 24 assists for 56 points. Originally a second-round pick (53rd overall) of the Maple Leafs in 2019, Robertson’s time in Toronto might be coming to an end soon. Getting a new contract signed, even for a year, takes away another hurdle to cross for interested teams.

Brewers righty deserves consideration as dark-horse Cy Young candidate

Brewers righty deserves consideration as dark-horse Cy Young candidate

The Milwaukee Brewers' trade with the Boston Red Sox early in the season flew under the radar. The Brewers acquired former top prospect Quinn Priester from the Red Sox, sending outfield prospect Yophery Rodriguez to Boston on April 7. Pitching prospect John Holobetz was sent to the Red Sox on May 5 to complete the trade. Priester had been expected to be a top-of-the-rotation arm, lauded for his athleticism and plus fastball and curve. However, he struggled during his time in the majors in 2023 and 2024, posting a combined 6.23 ERA and a 1.555 WHiP over 99.2 innings, striking out 69 batters with 41 walks while serving up 19 home runs. Despite a solid outing in his only appearance for the Red Sox, Priester remained in Triple-A as nothing more than pitching depth. That changed with his arrival in Milwaukee. He has exceeded expectations, either as a traditional starter or following an opener. Priester has posted a 3.15 ERA and a 1.190 WHiP over his 114.1 innings for the Brewers, striking out 93 batters with 38 walks. Opponents have mustered a meager .228/.294/.382 batting line in 471 plate appearances with just 13 homers. The Brewers' 64-48 record entering Tuesday is the best in the majors despite a nondescript rotation. While Freddy Peralta is a top-of-the-rotation arm in his own right, staff ace Brandon Woodruff missed all of 2024 and most of the first half of 2025. Pitchers such as Chad Patrick, Tobias Myers and Jose Quintana are back-of-the-rotation arms at this point. The Brewers needed someone to step up with Priester being the unlikely hero. Pitchers Paul Skenes and Zack Wheeler are the prohibitive favorites to win the National League Cy Young Award. BetMGM does not have Priester listed as one of the 10 most likely candidates to take home the hardware. However, Priester's performance, coupled with the Brewers' success this season, is worthy of attention. If he can continue to perform at this level, Priester deserves at least some consideration on the ballot.

Jerry Jones vocal in defense of handshake deal not being honored by Micah Parsons

Jerry Jones seems to be a firm believer that a handshake deal is as binding as any written contract. The Dallas Cowboys owner has maintained his stance that he had reached a verbal agreement with Micah Parsons on a contract extension back in March. On Tuesday, Jones was asked by NFL Network’s Jane Slater about the agreement not being put in writing. The 82-year-old claimed his initial acquisition of the Cowboys in 1989 started with a similar handshake deal. “I bought the Dallas Cowboys with a handshake,” Jones said, via The Athletic’s Jon Machota. “It took about 30 seconds. I gave the number, shook hands, the details we worked out later. As a matter of fact, one of the details involved a lot of money and I had to flip a coin over that. But the fundamental, ‘I’m buying and you’re gonna sell it to me for that range,’ that’s done. And those are done with eye contact and handshake. “Just so you understand the way that I communicate with people that I negotiate with. Let’s leave it at that. There’s no question that in the case of a player contract, you have to have it in writing. All parties do. We have a contract in writing, yet we’re still talking about renegotiating, so so much for that.” Parsons does not deny that he talked about contract terms with Jones in March. However, the star linebacker claims that he did not believe the conversation to be a formal negotiation. Parsons asserted in his trade request statement that he believed the conversation was going to be about team leadership before Jones shifted gears to talk about an extension.

Raiders Named Team That Might Be Willing to Pay Price for Micah Parson Trade

The Dallas Cowboys aren't eager to trade star pass rusher Micah Parsons since he recently requested one, but if he flatly refuses to play for the team ever again, there's not much they can do. If the Cowboys start to consider a trade, there will be no shortage of teams trying to get him. However, only a handful of teams could realistically trade for him and then afford to give him big money. While the Las Vegas Raiders already have Maxx Crosby on the roster and under a massive contract, they are a team that could have the means to swing a deal for Parsons. What Will Parsons Cost in a Trade? In order to convince the Cowboys to trade Parsons, it's going to take a massive offer. Ralph Vacchiano of Fox Sports spoke to some people around the NFL to get an idea of what the cost would be. "You’re talking about the best, most consistent defensive player in the game," an NFC personnel executive told Vacchiano. "And it’s possible he hasn’t approached his ceiling yet, especially as a pass rusher. That’s got to be worth a couple of first-round picks. "Maybe more." The executive went on to tell Vacchiano that Cowboys owner Jerry Jones could even push for three first-round picks. Should Raiders Trade for Parsons? If the Parsons does end up costing three first-round picks, then the Raiders can't realistically consider that. There are too many holes on the roster, and they may want to use one of those picks on a quarterback in the near future. That said, Vacchiano believes that the Raiders are one of the teams that could have the means to pull off a deal. "A great way to do that would be to build one of the most dominant pass rushes in the NFL, which might be what they have if they paired Parsons with Maxx Crosby," Vacchiano wrote. "Those two have more quarterback pressures than anyone else in the past four seasons. "There’s still a long way to go for a team that went 4-13 last season, and Parsons alone won’t make them a championship contender. But he’ll make their defense instantly formidable. And with about $38 million in cap space this year and more than $100 million in 2026, the Raiders can pay Parsons and still have a lot left over to add more." Parsons and Crosby would form a ferocious pass rushing duo that might be one of the best in NFL history.
