I don't think you're gonna ever see a big man be the clutch player most people like. Garnett plays the same from the beginning of the game to the end, which is very well. He's probably the most consistent player in the NBA. He's not the kind of guy who is gonna run around without the ball searching out open shots. He's the kind of guy who sets up in the post, or runs the pick and roll. He's not geared for the traditional "clutch" player. That role is more geared towards guards who can run all over the place with the ball from one end of the court to the other and make the shot. Arenas might be the best clutch player of all time in my eyes, and guess what, he's a guard.
Just my opinion:
Duncan = best player on the Spurs
Parker/Ginobli = who the Spurs go to for a clutch play
Garnett = Best player on the Celtics
Allen/Pierce = who the Celtics go to for the clutch play
I could go on and on about it, but when it comes down to the wire, your guards are counted on to make the big play
