OL Josh Knipfel, Iowa State
The offensive line is wide open.
And Knipfel is just their sort of guy — he was a co-captain and started 39 straight games. He’s also a massive 6’6″ and 309 pounds. If he shows he can play inside or out, the versatility alone might earn him a backup job because it can help them crunch roster numbers and keep somebody else at a different spot.
