FWIW, here's Belichick's view on why OL play is poor these days.
"“I just think in general, fundamentally it’s difficult to play on the offensive and defensive line,” Belichick said. “You’re playing a contact position with pads, and you’re practicing it without pads the majority of the time. That usually develops a lot of bad habits, and a lot of the techniques that a player would have the chance to work on and improve with pads, that opportunity just isn’t there without pads.
“So it’s hard to improve at those positions when, a lot of times, you’re practicing techniques that are really not the ideal technique or, in some cases, incorrect, and it just develops bad habits, especially on the offensive line. . . . [W]ithout being able to practice, [this] favors the defensive players a little more, whereas the offensive unit has to work together and be able to block things at more of a game tempo with pads and penetration and combination blocks and things like that. It’s just hard to simulate those and hard to get the timing of those when you’re just standing up watching each other without pads on a lot. So, I mean, look, we’re all coaching under the same rules, but I think it’s harder, especially at that position, to improve when you really can’t practice your skill.”
http://profootballtalk.nbcsports.com/20 ... line-play/If this is a common sentiment around the NFL, you don't have to put on your Spock Ears to logically deduce that a simple blocking scheme would work better.
Never more true than when you have a very young group at OL who need to learn the basics.
Taking from his comments, I wonder if our OL may be getting bad habits in both ZBS and Drive blocking thus complicating the learning curve even more.
