About offensive linemen. He liked his guards and center to be around 6'2"- 6'3" to create a low center of gravity and to be able to get under the pads of the defensive linemen. He thinks a tall OL is more apt to have injuries because they can't get under the pads of the DL. I think that is why Steve Richardson is so successful. I looked up the height of Esslinger and Setterstrom two of his better OL and they were both in the range Mason quoted. I think our OL except for Bobek are all 6'5" or better.
