I think all service academies have prescribed weight restrictions per height.  High-ranking officers have occasionally referred to these as "beauty pageant restrictions," but they still exist, with some slight exceptions for linemen.  However, I don't think the exceptions bend enough for the academies to recruit enough competitive linemen...or maybe it's that the blue chip high school line recruits don't see four years of post-graduation active duty service in their future if they want to play in the NFL.  Also, could they even get enough congressional nominations...?  (Geographic diversity?)  So with an undersized line, you run an offense based on discipline, misdirection, and speed.
