TB, I'd like to think having Wallace on floor on the last offensive possession is a mistake that Boylan won't repeat again, being that it lead to gut-wrenching reliance on his free throw shooting ability.
He was out there in possessions we could have won against Orlando and Portland as well. He's made in 3 games (on multiple important possessions as we had chances to tie/win in overtime and regulation), so to assume he won't make it again goes against all evidence of what he's done. It was more critical in those games, because we were playing to tie a game as well. In this game, if we had missed then we'd have just gone to overtime potentially.
Instead, I think he'll figure Ben Wallace can hit 1 of 2 at the line since that's what happened, and we won the game. Considering this mistake has hurt us in 2 previous games already, possibly causing 2 losses (though it's a stretch to blame any loss on one thing like this as there were probably a 100 things that he could have done differently to cause a 1 point swing in an OT or double OT game) it's hard to envision him deciding it's a bad idea after it generates a win.
