If you had a 10 year trend you may have a point. It is good for rivalry smack but not much else.
But you could point out that in your two year window BYU has the #5 pick in the draft and a high second rounder (should have gone in the 1st). Actually I guess after today that is a three year trend.
But last year BYU had 4 players sign contracts. In the past 3 years that number is something like 10 players. How is that bad?
