He we will figure it out. He will learn to hit the bull rush, when he sees the OT on skates rushing back to mitigate his speed. His bull rush will be about leverage, not pure strength. I just havent seen him use his hands much or use a counter. Been straight sprint to QB or some kind of juke and go.
You are dead right on getting out of his pass rush lane (run game is applicable also). That was the double-edged sword I was talking about. You are going to have to live with some of that as a coach, because he can just make plays that other guys can not. He is on pace for double digit sacks. Texas has not had someone with 10 sacks going back to 2016 (cfbstats.com - 2017 Texas Longhorns Sacks, site doesnt go back further). He has 6 TFLs (1.2 per game). Only Ossai in 2020 (1.78 per) and Omenihu (1.29 per) have been better since 2016. Simmons is a freshman and not logging the same snaps as those guys (yet). You dont want to turn him into a robot and lose that play making ability. You have to try to rein him in a bit, but not too much. The biggest thing for him will be gaining the experience that helps him figure out when to break the rules.
