I don't know. I think that by the time you get to the NFL, as an O lineman, you really should understand pretty much every scheme and how to block it. I'm not sure how much coaching really needs to be done for these guys. Other than if something shows up on film where a guy is using awful technique or just plain missing what he should be hitting. Offensive linemen actually have to have some intelligence to play that position effectively. I feel like by the time you make it to this level, you really shouldn't need to be coached on how to block shit up.
Now, if the problem is motivation, I guess that's a different story. Is Lucas Patrick more motivated to do a good job with his current squad? Maybe. I really don't have an answer as to why these things happen. Then again, it's only two weeks into the season. Those guys have plenty of time to start sucking again.
