I don’t think Dave was that great at recruiting so Dennis would be an upgrade.
Dennis is a phenomenal recruiter. Of course, when you have Ohio State on your shirt it makes recruiting life easier. That said, he was able to pull the #1 QB recruit away from Texas Longhorns...and that recruit is FROM Texas. That's high level recruiting.
Also, even as a grad assistant, he was working with OSU QBs. That's what earned him a promotion to QB coach. Every single QB that was coached by him, and two are now in the NFL, has raved about Dennis. He's widely considered an up and coming star in the coaching world.
IF we are able to pull Dennis away from OSU (I haven't really seen any indication that this is likely) to join our offensive staff, that's a homerun for CGC...and he needs homeruns right now.
