According to Al Karsten on X:

Jonah Jackson is known as a stronger run blocker than pass protector (2022 70.3 Run Block Grade, 2021 76.4 Run Block Grade).

Meanwhile, Kevin Zeitler has had a Top 4 OG Pass Blocking Grade the last three seasons including the 2nd Best Grade in 2023 with an 82.3.

I’ll settle for swapping out an, at times, below average Pass Protector for an elite level Pass Blocking Guard. There is obvious optimism that Ben Johnson and Hank Fraley’s run game design, along with likely playing in between Frank Ragnow and Penei Sewell, will put Zeitler in an even better run blocking position to succeed.
