The 'Chaney thing' is total speculation based on very tenuous threads. So, don't get too antsy.
I get the heartburn over hiring someone who worked 'over there'. But Chaney isn't a 'UGA Guy'. He's been all over the place.
He was good enough to get Ugag to within a TD of a NC with Tr.Fr. Jake Fromm. The knock on him from Dwag folks was that his play calling was too predictable. That he relied on out-talenting other teams, running the ball on 1st down, etc. Which, is what you can do, successfully, with their roster. A lot of them were happy when UT offered him more money. But their offense has been worse since he left. The problem appears to be Smart's conservative offensive philosophy. This year, they brought in Todd Monken as OC, who's a Big12 spread guy off the Mike Gundy tree. Yet, Kirby still has them running a super vanilla run-first offense with Stetson Bennett. Rumor has it Monken may leave after one year.
Chaney's career trajectory tarnished a bit from being caught up in the Pruitt situation at UT. But he's an experienced and well-regarded OC. He's a guy who probably should've gotten a shot to be a HC. But he's made some unlucky career moves - working for both Dooley and Pruitt on doomed staffs at Tennessee. He's exactly the kind of experienced and proven OC that could take on the GT job. If he improves things, he looks like a genius and it's a good move. If Tech is no better and CGC gets the boot. He'd make a decent interim coach. Probably doesn't get the blame and he's onto his next gig.
