Sean, you're extra emo per the usual, but you're a good fella and I have no problem if you thought he shouldn't have taken that shot.
Fact is, this one of those rare games where Manu was actually shooting pretty well from downtown. He was 2-4 up to that point.
What's more, the Heat is a very solid defensive team. We 'wasted' 14 secs on the clock on a solid, well thought out and executed offensive play, and we ended up with with the exact same result as Manu shooting that 3: nothing.
As a reference, look at that clutch shot by Tony. He burned down the clock exactly until 11 secs too. Then we went to execute. Was it the play we wanted? No. Were we extremely lucky to even get a shot up? Absolutely.
So you need to put things in perspective here. We're not playing the Warriors or D-League Lakers anymore. We're playing against one of the top, if not the very best, defensive team in the league. So yeah, executing anything with 11 secs left, and after a broken play it's difficult.
Ultimately, that's why Pop puts the ball in Tony's and Manu's hand (Manu was actually handed the ball in the play right after, the high pick and roll with Tim where he was fouled). When our offensive breaks up, they're the two guys that either have the big balls to take the big shot, or make lemonade out of a lemon play.
Now, while I disagree that was "ill advised" or "hardly ever go in", that's your opinion and that's fine by me.
What's plain bull is to say that shot had any bearing on the Heat closing down the lead late in the game, IMO. We had a fairly poor first half defensively, some big mistakes like that Allen 3 pointer foul, etc that are much, much bigger than a single shot. That's all.
