Actually… I like Derek, but if your looking at it this way (which is garbage math anyway - but Nevermind that for a minute) - the reality for Derek is:
Games his +/- was bottom 2 of any position players:
Worst:
Illinois, WF, Purdue (g2)
Second worst:
SHU, OSU, Iowa, Purdue (g5)
So in summary, he had the worst or second worst +/- on the team in 7 of our “real” games.
I’m not looking to pick on Derek. The point is it’s a garbage stat since it’s a blended average. If you look at it game by game for Derek only it can tell you which games he was good Derek and which ones he sucked. That’s about it.
