A darkhorse contender for a transfer portal quarterback like Maalik Murphy is Michigan football. The Wolverines recruit Murphy coming out of high school and, depending on what happens with J.J. McCarthy's NFL draft decision, the Wolverines could have a starting job open.
Michigan might be losing McCarthy, Blake Corum, Zak Zinter, Mike Sainristil, and a number other starters, but there is going to be talent and it's going to be an attractive place for quarterbacks.
Murphy would have to wait until McCarthy makes a decision, but if the Wolverines don't wind up with Dante Moore, Murphy could be an ideal option for the Wolverines.
Unlike Moore, I don't see Murphy wanting to wait another season on the bench though. That's why I don't see Michigan as a likely destination unless we know what McCarthy does, plus I see Moore as being a higher priority for the Wolverines.
