What are you talking about? I'm a huge Celtics fan and the one thing no one can question about Walker's game is whether he brings a spark or not. He's such an emotional player, you don't think it was coincidence that when we acquired him from Atlanta last year we immediately went on a run that just about locked up the Atlantic, do you?
Apparently you haven't watched him in Boston much. You can question his insane shot selection or his tendency to drive and lose control, which usually ends up as a charge. However, he plays with so much emotion it's impossible for him not to provide a spark even it's not directly. Last year, he willed Paul Pierce when it looked like he was running out of gas at the end of games, and I'm sure he has that same positive impact on Heat players.
