Perhaps the primary reason that I'm wondering about this is Whit's interview with Cowheard about how much the circumstances have suddenly changed because so many teams now have 2 really good edge rushers. In fact, Whit says he's dropped weight to the 310 range in order to combat it, when he used to play considerably heavier.
Further, that the edge rushers are so athletically and technically advanced, that they can bull rush, speed rush, have counter moves, etc.
Watch the Green Bay vs. Chargers game to see it in action. Green Bays two OTs are considered in the upper echalon. But the two incredible edge rushers of the Chargers completely outclassed them. Green Bay's OTs didn't get worse; the edge rushers have gotten better.
From my standpoint, the RT was a different position because the really good edge rushers tended to line up over the LT. The RT was more of a run blocker as most teams are right handed when it comes to running the ball. No more. So what Havs has been in the past doesn't necessarily fit the circumstances in 2019 and beyond. That's not a bad reflection on him. It's just like MLBs used to be primarily nasty, big, run stuffers but today they have to be more nimble to be involved in the pass protection part of the game.
The NFL changes fast and the colleges are putting out amazingly good defensive football players because so many of these gifted players are starting as freshmen whereas that didn't happen very much even just a few years ago. I think the coaching is also a quantum leap beyond what it was even 10 years ago.
