How's about search feature that allow you to find what's type of players and height/weight that you want to recruit ?.
As for Army/Navy, they have least restriction for height/weight because they don't require you top pilot warplane while they have 300 pounds or 6-6/6-7.
Navy has friendly requirements than AFA or Army which was large due to David Robinson.

They have more flexible for BMI than Army or Navy.
Army might have most restriction for BMI ,but they do make expectational for football players.
However, I noticed that all 3 have rather small DL than FBS average. they're at between 230 and 260.
