Know a guy who was on staff with Collins at Tech (very high up, off field role, but did talent eval) and I said "dude idk how Collins didn't automatically get 5yrs. They had to re-recruit their entire roster because of the offensive changes."
And while he agreed, he pointed out a lot of things that were an issue. For instance, we were discussing a top-100 c/o 2024 guy who is an OL and an absolute beast (top 75 overall). I asked why he wasn't higher and he said it's a technique thing. Fair, then he pointed out "yeah I was told we couldn't offer him because he's too raw and we need guys who are ready now... I then told coach Collins 'every SEC team is beating down this kids door, he's from FL, why wouldn't we at least offer him...?"
Collins apparently said "I need guys who are college ready and can contribute immediately" ... I look him dead in the eyes and go "Coach, your boy coach collins may be a little misguided as to the prestige and allure of Tech. In your years there you probably had what? 10 guys who came in ready to make meaningful contributions as a true frosh?" and he goes "Well, we played about 25 guys who were nowhere near ready, and about 8-10 were actually ready"
Guess my point is yes, it is probably time to move on, but Collins was given a team he had to completely rebuild/restructure so I am not surprised in the slightest he has not done well.
