Luke Joeckel of Texas A&M is 6'6", 306. Oklahoma's Lane Johnson is 6'6", 303 ans Eric Fisher of Central Michigan is 6'7", 306.
The fourth, Alabama junior DJ Fluker, is built differently. He is listed at 6'4", 339 and he is every bit of that. Good luck trying to get around him. John Mara wanted to improve the club in the trenches. Fluker can do that just by showing up.
