In every series we have had players rise because of matchups. Against Milwaukee it was Semi, giving us huge minutes against Giannis. Against Philly, Baynes has been irreplaceable - we needed him to bang with Embiid for ~20 minutes a game to absorb the contact and the fouls, making Embiid work and play inefficiently.
Who will it be against Cleveland?
I have been down on Marcus Morris lately, but I am hoping this is his time. I picture Brad telling him before game 1: Marcus, you are going to win this series for us. On defense. You're going to play 20-25 minutes, and for every minute you are in you are going to give LeBron fourth-quarter intensity defense. Leave it all on the floor. You are going to play physical all game long. And by the end of the game, when they need him in the fourth quarter, his legs are going to be gone. And that is how we win the series.
We'll get more minutes from Semi and Jaylen (hopefully, if he's healthy) and others. But I think this is the Mook series.
