I go back and forth. There are times when their protection is pretty good, relative to giving AM having time to pass or run. There are times in the running game where the RB has some options, inside and out, depending on the down and distance.
However, there are times when there are lineman COMPLETELY missing their assignment. There are plays where the lineman in question is just lost. That's a between the ears issue more so than S&C. There seems to be a disconnect with "This is what we are trying to do on this play, in this situation". That's why I look at Red Zone particularly. Overtime. Lot's of people in the box to deal with, run or pass. Not sure we've excelled there.
If you watch the games, the one on one's aren't so bad. Interior D line and DE's have been blocked ok. The LB's have given us fits at times. The O line is learning how to play games. Learning how to perform outside of simulated situations. I'm confident they know how to block. I'm confident they know how to follow the playbook. Pretty sure they know what's a hold and what isn't. They are probably well conditioned. Sometimes you just have to get in the way, other times you need to have superior technique and leverage. They are figuring some things out. Sometimes the TE has a responsibility related to the oline and this takes some time. I think a lack of quick slants and quick fly patterns makes the line be 'accountable' on every single play. I'm sure someone will come on here and say they've seen these quick plays, but I haven't. I think the line is expecting some quicker throws at times and think they have successfully blocked for the called play, but when reads aren't made or guys aren't open, things break down.
I don't think the line was intended to be a strength. Yet. But the things that were supposed to be strengths really haven't been. So they get the spotlight more often than they should.
