I like Pierce defending top players. He is a really good defensive player.
His all-round game is needed for the team to be successful. Not just his offense. Not a dominant enough offensive player anymore for the team to revolve around like that on the offensive end of the court.
While I agree with this, I also think his defense and rebounding have taken a real hit this year. It shows up in spurts (much like his offense), but they are fewer and fewer each season.
If we are talking an end of game situation, then yes, I want Pierce on their best wing scorer. However, I think getting him rest earlier in games might not be a bad thing.
I also think I am done with the Terry (and Bass for that matter) starting experiment. It helped get them on track as Sully and Lee got more comfortable in the system, but I think its time they go back. That will give them more defense, rebounding, and overall grit in the starting lineup, and more explosiveness off the bench.
