I've been pounding the drum that a lot of it is the under QB vs spread stuff. When you run spread your linemen are more on an island than when you run under center, so I agree that a lot of it is scheme. That said I still think Jonah is very average and in this division with Garett and Watt (and the Ravens having the most sacks in the league) you need to be a bit better than average. I was on the train that said Jonah is showing up at RT, and then in both Steelers games, I saw Watt just abuse him. I get that any draft pick might be a risk there, but it's a risk I'm willing to take.
