Wow - I am surprised to see Tony Allen's name mentioned on a thread like this.. 
Really?
Or Antoine, for that matter..
Why?
A thread like this is everyone's opinion..with that being said, I loved Antoine's game. He had big shoes to fill here until Pierce came along and got better in the league.
Sure - Antoine frustrated me some times as a player..to be honest, I thought he could play in the post more, but that's his game. He played the same way in Kentucky, so we knew what we were getting when we drafted him with the 6th pick that year.
Overall, though, I loved Antoine's game. Red and Tom Heinsohn did, too. Sure he was a volume shooter, but who else was going to take shots (and make them) for the Celtics back then?
When Antoine was hot, not many could stop him (49 pt explosion in Washington to carry Boston to a win).
He displayed his Leadership skills, even firing Pierce up during that playoff run back in 2002 I believe..him and Pierce carried the team far during that unlikely playoff run.
Antoine was a Leader. And he was even instrumental in Miami's Championship title game, netting 17 pts off the bench.
Has he made mistakes since then? Sure. Like we all do. But in my opinion Antoine shouldn't be on this list, Just my opinion.
And Tony Allen? In my opinion he has been one of the steadiest players for us since he came back from his injury. He is one of our better defenders on the wing, just like another poster stated here.
TA has played big for us in Big Games (Christmas day and the LA game in Boston). Sure we lost the LA game, but he gave Kobe problems.
Does TA make mistakes in games? Sure..but no more or less than other players I think.
Just my take.
