Ok, I have no inside info, but these names seem like a stretch. Sure, this is where you start on the off chance, but I don't see them happening.
For instance, Wellner/Caputo - let's say they both want to be a head coach. Where do they stand a chance of that happening? At programs that just played in the NC, and probably will be in a similar place for the next few years or leaving for, frankly, an underperforming in-conference program? And the whole "you can replace Gait" option makes no sense. If Cuse starts doing well, Gait is not going anywhere. If he fails, well, you don't give the job to the assistant.
Same argument for the the head coaches on this list. If you want to move up to a bigger program, do you do that from a HC spot at a successful mid-tier or as an assistant at Cuse? Probably the former again.
Finally, the whole "back up the $ truck" argument. Listen this is not SEC football. There is no money truck. Maybe you have budget for $25-50K more and maybe that will be enough to get one of these guys to move. But unlikely.
Point being, I don't see any of these guys coming.
