While none of us know exactly what happened in meetings or conversations between RR and Mallett and between Hoke and Denard, my sense is that it was something like this.
RR - Ryan Mallett you are one of the top pro-style quarterbacks in the country. I don't really see how you will fit in the offense I intend to run, even though I have no one else available to me that can run it. I hope you stick around, but if you decide to leave I will understand.
Hoke - Denard Robinson you are one of the top dual-threat quarterbacks in the country and have dilithium speed. I would be a fool not to find a way to take advantage of your skill set and experience, even though I have Devin Gardner (and nobody else) to work with. If you leave Michigan you would have to sit out a year and you would not get the value of a Michigan degree. The team needs you, I need you, please give me a chance to find a way for us to be successful together.
