I understand what your saying that a rookie like Walker should not be playing in game 5 of a 2-2 playoff series. But, don't think Moore should be playing in a game except for garbage time either. I actually think that Walker may be a better option than Mikki Moore, that is not as much a compliment of Walker but a shot at Moore.
This is just another example of how bad the Celtics depth has gotten during the playoffs. Before the injuries we could look at moving PP, etc. but we have to play somebody off the bench. I can see going small using PP and having Marbury and Rondo in at the same time, but there is going to be part of the game where one of TA, Moore, or Walker has to come in and get mins. In my opinion we have tried TA and Moore and the results have been poor resembling what I would expect from a rookie. I say put in Walker and keep him on a short leash, he is a guy the Magic haven't seen he could end up playing pretty well.
