Anyone that Hoke signs at this late date will be (at best) a mid-level three-star — someone totally unready to play Division I football. If said QB sees the field in 2011, it will only mean that both Devin Gardner and Denard Robinson are injured, and it won’t be pretty.
For the 2012 class, I am sure that Hoke will be looking for a 4+ star kid with a much higher ceiling. With a year to work on it, he is probably going to find that kid. That means the QB he signs this year, if any, will be a transitional figure: a David Cone type who is unlikely ever to see substantial playing time in a Michigan uniform.
The thing is, most recruits are going to look at the depth chart and see these same facts, which limits the kind of QB that Hoke can hope to get — basically, those who realize that in exchange for a Michigan degree, they are probably going to spend four years running the scout team and holding a clipboard on game day. That's not a bad deal, but a kid who wants a serious likelihood of starting will probably choose to go elsewhere.
