Andrew Wiggins ruins Donovan Mitchell's buzzer-beater with one of his own

But the Cavaliers focused too much on Norman Powell, who had 33 points, and lost track of Wiggins on the final play. He streaked to the hoop and finished an alley-oop to get the Heat the win.

The Heat have new go-to players this season without old stars

In previous seasons, the Heat in crunch time would have gone to Jimmy Butler, who was traded to the Golden State Warriors last season, or Tyler Herro, who has been out all season after surgery on his foot and ankle.

They're getting 24.5 points per game from Powell, obtained in a trade from the Los Angeles Clippers. Wiggins, who had 23 points Monday, is averaging 17.8 points and shooting 40 percent on threes. Jaquez is averaging 17.5 PPG and he had 22 points, 13 rebounds and seven assists in the win.

The result is that the Heat are tough to guard in big moments. Miami scored 12 points in OT, with five different players scoring. Eight different Heat players scored in the third, when Wiggins nearly matched Mitchell's 13 points with a dozen of his own.

It's a testament to the Heat's egalitarian system, where coach Erik Spoelstra has trusted his players to read the defenses and react, despite having no superstars. Of course, Spoelstra showed he can call plays when he needs to with the highly-rare game-winning alley-oop play.

The Heat are 7-4 and their All-Star guard hasn't played a single game. It took them until the final milliseconds Monday, but they showed they can hang with any team this season.
