Lots of thoughts here.
First off. Are you saying Marion will never become smarter on the court? I am assuming Pippen played 3-4 years of collage ball. He also had an offensive genius in Tex Winter as an assistant coach. Marion went to a JUCO, then to UNLV. He hasn't had a solid coach to teach him basketball IQ yet. In fact, it is amazing that Marion is so unbelievably good without the basketball knowledge.
He is 24 years old. He has like 12 years of basketball ahead of him. The thought process behind resigning 90% of your RFAs is that they will grow into their contract. The Hornets did the same thing with Baron Davis. He had been a dissapointment till this year.
Anyways, even with Marions poor play this year, his numbers are still great.
18.4 ppg, 9.8 rpg (2.8 offesive), 2.5 asp, 2.03 spg, 1.79bpg, 43% fg.
He is #12 in Rebounds per game, #6 in steals per game, #7 in steals per turnovers, #7 in FT percentage, #17 in blocks, #10 in double doubles. He is ELEVENTH in the league in efficency rating.
Compare that to you man Paul Pierce,
23.7 ppg, 7.1 rpg, 5.7 asp, 1.53 spg, .78 bpg, 41% fg
He is #6 in ppg, #18 in steals per game, #13 in apg, with a TWELVEth place in efficency rating
Paul Pierce is the main man on the celtics.
If this is considered a bad year for Marion, his numbers warrant his contract by comparing him to the best of the league. Plain and simple.
