Our OL may not be as good as our DL.
I could easily see our o-line taking a big step backwards.
Losing Frederick really hurts. Partly for his ability but mostly for his brain and the calls he'd make when he saw things on the field.
Tyron can't make it through a year without missing at least 20-30% of the season anymore, and that hurts. And after 4 years of him missing that much time like clockwork, and him nearing 30, it's only a matter of time before the dam bursts and he starts missing half the year or most of the year.
So, right there, there's a strong chance we'll be worse and weaker and dumber up the middle. And there's a strong chance we'll be more exposed to edge rushers too, whether it's because we're compensating for the loss of Frederick by focusing resources on the middle of the line, or whether it's because Tyron breaks down.
And, let's be honest. We have no idea what the change in o-line coaching will make.
We've had really good players in the past whose careers were briefly de-railed by blocking scheme changes with bad offensive system changes or scheme changes. It happened in the early 2000's (it was surprising to a lot of fans when one of Parcells' first moves was to keep Flozell, because recent ill-advised scheme changes had fooled some people into thinking Flozell wasn't good). If the coaching change doesn't mesh well with the o-line, buckle up because it'll be bumpy.
One thing I'm curious about and haven't heard discussed much is this: weren't McCarthy's Packers' o-line the ones who someone famously made a YouTube video about where he dissected an unusual tricky technique of pass-blocking they had, designed to help them get away with holding? I forget what the trick was but it was obviously something sketchy.
If we're gonna have our guys use a shady gimmick like that, I can't imagine it won't be called more often and won't mess up some of the players' techniques because we'd be wasting precious time teaching them a gimmick instead of real fundamentals. It's like the scene in that Mighty Ducks movie where the hockey coach wastes a day of practice teaching his players to flop and fake injuries to scam more penalties.
