I think this guy (Fleck) could sell ice to eskimos. against a bunch of 18, 19 & 20 year-old kids, it's no match.
I admit I have not watched WMU play enough to have a sense of Fleck's offensive philosophy - and that assumes he brings his coordinator with him. If it turns out to be a new O-coordinator, it's really hard to say what type of offense they plan to run - and what set of QB skills will best fit that offense.
As of right now, all you can do is take the guy at his word. If he says Rhoda will have a fair chance to compete for the job, then that is what should happen. If it doesn't happen, then you've got problems.
