Grading Chiefs' Biggest Moves Entering Free Agency Day 4

The Chiefs needed a standout running back in the backfield with quarterback Patrick Mahomes, and they did just that by signing Walker to a three-year, $45 million contract, making him the highest-paid free-agent running back in NFL history. The Super Bowl MVP will have a chance to run behind the best offensive line he's played with in his five years in the league, with the opportunity to be one of the engines of Kansas City's offense under offensive coordinator Eric Bieniemy.

Alohi Gilman, safety — Grade: B+

This signing has flown under the radar, to my surprise, as this is an impressive player overall that the Chiefs were able to snag on a three-year $24.75 million contract. Gilman is a versatile safety that fits perfectly with what defensive coordinator Steve Spagnuolo wants to do in terms of coverage disguises and unique roles or assignments for his defensive backs to create confusion for the quarterback. Gilman isn't overly flashy, but a sound player to replace Bryan Cook nonetheless.

Khyiris Tonga, defensive tackle — Grade: A

This is exactly what the Chiefs needed along their defensive front: a defensive road-grader with no regard for the guard or center in front of him. I thought Tonga was an underrated player for the New England Patriots this past season and made exceptional plays against the run. Kansas City should still pursue depth and quickness at the position, but Tonga adds a great element against the run.

Travis Kelce, tight end — Grade: A

There's not much to say here. Kelce, a future first-ballot Hall of Fame tight end, is going for his fourth Vince Lombardi Trophy and hopes to ride off into the sunset in his 14th season with a ring No. 4 (well, technically five if you count the upcoming wedding).

Tyquan Thornton, wide receiver — Grade: B-

Thornton's market might've been thinner than I expected, considering the potential need for a vertical playmaker. He returns to Kansas City, where his career was revived last season. He should remain a key depth piece within the wide receiver room, but he is more of a pass-catcher who thrives in one singular area, albeit an important one.
