I think everyone wants the raps to have a distributing PG, but this writeup makes him seem like a Jose who can't shoot. If he does have penetration abilities that makes him different than Jose, maybe like Rondo without the D. Although Casey's system can cover up and help any defensive problems he may have.
I take this analysis of him with a tank
of salt as this is the site that said that quincy miller would be drafted in the 2nd round and as of february 24th have him as the 30th pick in the draft going to Miami. Although they haven't done an update on marshall and how he's doing this year, nbadraftexpress is much much much better than nbadraft.net. As of March 1st, nbadraftexpress has him as the 18th pick in the first round.
nbadraft.net has MKG at 9th, nbadraftexpress has him at 3rd. Most people agree MKG goes top 5.
