As far as lineman go, they don’t really get a running start and they are typically matched up with someone their own size or smaller. They don’t get tackled to the ground much either.
Linebacker is a whole different animal. A lot of big collisions, contact on every play, getting run blocked by guys sometimes 60 to 100 lbs heavier. Having to tackle running backs at speed. Yeah, that would be a good project as well.
