There's probably something to be gained for an offensive lineman. But in Long's case, he needs to learn how to be an offensive lineman. And the only reason he was doing that nonsense was because rules prevented him from actually practicing with the team. I would assume the guy is behind, given his raw status and lack of OTA time. Hub may be a curmudgeonly old coot, but it probably isn't a stretch to say Long is having issues with his hand placement and other technique. The other guys have spoken positively, but only in a "he's really strong" sort of way. Also, Hub only wishes it was PFT that folded, he was PFW.
