Oh, lol. I just realized he is a G. I thought he was a OT for some reason. I still think the advice I gave is fairly universal. You may consider taking confidence higher at some point since it is a major skill but for now it trains well with vision.
Back to VAs.
Stonewall is very popular and I like it as well.
Great blocker is a safe VA for if you can't pick one at any point in your career.
Workout warrior is not as good as great blocker because it gives you 0.3 per VP but still it is considered a safe VA.
Pass Blocker is kind of meh. I personally am too afraid to try removing it but often wonder if it even works.
Showboat blocker is great if you get 10 or more pancakes per game. It will only help to improve your numbers imo.
Thats all I can think of as O line VAs are kind of limited.
