Player B is Ben McLemore,
Player A is O.J. Mayo.
I pretty much throw up in my mouth whenever McLemore is listed as a possibility for the Cavs for this reason.
I will admit that overall (TS%) McLemore had a better year than Mayo's freshman season but the argument that his athleticism will allow him to attack and finish in the NBA once he learns some more aggression is rooted in the fallacy that athleticism is the primary component in this skill. Mayo is, I believe, the perfect counter argument for McLemore, He has all the measurables you could ask for in a shooting guard but can't put it together and generate better than average offensive play.
Basically I don't want any part of McLemore.
