I just don't get the semantic games people try to play, whether it be Max, Tommy, Parish, or I guess Ryan.
Saying that Pierce is the "best offensive player" because he's got the most versatile game or is the best manufacturer of his own points is like saying that Nate Robinson is the best player on the Celtics, because he's the absolute best in the NBA at one skill, which no other current Celtic can claim. I guess you can make the argument, but it twists the meaning of words to the point of ridiculousness, in my opinion.
Unfortunately I didn't get the opportunity to watch Larry when he was playing, but those guys did on a nightly basis. I'll take their word on it that Pierce is the more gifted offensive player. He can do everything you can ask for on the court when you think about it. He can catch-and-shoot, create his own shot, run the break, drive, set up teammates, you name it. The Legend could do all of them too, but the areas he was greater at than Paul aren't by as wide a margin as Paul is better than Larry. I guess.
Paul really is an underrated player. The bad teammates and coaching that plagued his career early really affected his all-time status, much like KG.
His shooting touch (from anywhere), dribbling skills, basketball IQ, clutchness, and passing ability make him a very unique player. Compare him to say, LeBron James, and even though LeBron's PPG is better, he is nowhere near the offensive player that Paul Pierce is.
