NDSU CA Forever's analysis is a good one.
Our OLine is long and active, and this offense requires them to work all types of pass pro but also to get out in space and block in free space. Davis' run game is predicated on spacing and finding daylight, this is not Ron Gould's run game. You could call it a zone scheme, but it's a different animal. I'd be interested to see if #72 Riley Gallant plays a little more on Saturday. He spot started against some tougher defensive lines in '18, Idaho State, @ Eastern in the playoffs, and opened up some huge holes in he power run game on the edge at RT. Gallant was one of the last Ron Gould guys who stayed with the system after Hawk came on...he's a senior. After the switch, the Aggies currently have 3 senior OL on the roster. I don't think any of them start.
As for Maier, I've been happy with his senior year thus far, he has been a little craftier in the pocket than the previous two years. That being said, he is not Tim Tebow...in the sense of being a pure bread athlete, runner, scrambler...but thankfully he can spin it.
