This whole exercise is projection.
1.) Your first post said some version of "If he'd just somewhat consider embracing blocking," which not only said he hasn't, it means he hasn't even made the steps to be "serviceable." No one said mauler but you, and yet now you're moving your own goalpost.
2.) Hall's presence in the discussion is he's a transfer that didn't get the time he expected, and he bolted. I'm aware Niblack isn't a cancer, hence my entire sentence about him not attacking a parking boot or saying loony shit. That being said, not learning the playbook after a year in the program DOES seem like a bit of a warning sign.
3.) I don't know, I think a high-ish profile transfer who, what was it you said, had proven productin for a major program and we witnessed kick our ass for 'Bama could reasonably be expected to come in, learn the playbook, consider trying to be a serviceable blocker, and challenge a 5th year guy with less talent and ability for playing time. This doesn't seem like an unrealistic expectation from anyone at all. Is your belief that we paid him NIL dollars to transfer here to ride the pine all year? Becuase I'd argue the staff expected more as well.
I'm not saying I want the guy to go. But if he did, I'm not going to lose any sleep over it.
