Barcello should have never passed it to Johnson in the first place. Right up against the baseline, right under the basket, with two defenders bumping him from behind? Who wouldn't have turned it over? That's probably the second worst spot to inbound the ball against a pressing team, right after the corner.

As for the rebounds, everyone was struggling to rebound the ball, it's not like rebounding only falls on one player. I'm sure Johnson wishes he could have corralled though, but at least he put himself in a position to make the play. He'll learn. He's just a sophomore after all. Gideon George actively knocked a few rebounds away from teammates, gifting extra possessions to SF, but because it happened earlier in the game, no one remembers it. Harward wasn't cleaning up the defensive glass like his usual self.
