re: How good was the LSU OL in 2019

They weren't the best but good enough. A lot of plays LSU was sending 5 receivers including the rb. This leaves your o line susceptible to every blitz package you can conjure up on defense. Burrow was other worldly escaping pressure and making a positive play.

How it relates to 2020. Myles will need a cleaner pocket than Joe. I think you'll see a lot more shorter passes because Myles doesn't glide around the pocket and wait for the longer routes to develop. LSU will run the ball more as they should. I look for an improved o line this season. By mid season the continuity should be good.
