You make very valid points. Chris Allen has some of the worst shot selection I've ever seen for such a highly touted player. His problem is he chucks garbage at the hoop and it magically falls, so that gives him the go ahead to shoot that same garbage 5 more times before he makes another.
Here is a stat for you: When Chris Allen shoots above 33% from the floor Iowa State is 11-1. His shot attempts directly correlate to Cyclone victories. In my opinion, the less he takes, the better chance we have to win. Those shot attempts are much more effective when given to Scott Christopherson and Royce White.
That said, this team has been playing extremely motivated lately, and I think you'd be a fool to lay the -2 on Oklahoma State. Don't overthink this guys, its a +2 or no bet. BOL
