Bullsqueeze. Frank left Billy C more NFL talent than Billy C left for Bo. You must've been drinking some funny koolaid back then.
I looked that up, thinking you were wrong. But it's actually closer than I thought. I think the four years' of NFL drafts following Solich and Callahan captures most of the talent left on their teams when they left, although there are probly some exceptions. I crossed out the JUCOs who weren't leftover from the previous coach, including: Zac Taylor, Ola Dagunduro, Carl Nicks, Steve Octavien, Zackary Bowman, DeJon Gomes, Lavonte David Yoshi Hardrick. Probly some others on this list who weren't left over from the last guy.
