Williams is actually playing more effective this season than he did last year, he just isn't getting the same touches. In his 20 games played last year, he averaged about 7 shots a game. He's down to just 4.5 a game this year, despite a much better shooting average. (41% last year, 47.5% this year).
I'd argue they aren't using Williams enough. Maybe he could meet some of those expectations if he had guards that could throw an entry pass.
It's cool though. I get these guys are on scholarship, it's D-1 athletics, etc etc. I've been around enough to get it. I just don't get the praise of Arledge when for the first 2.5 years of his Mason career he was a no-show and then plays 18 pretty good games and he's a hero.
