BYU might be the only team in CFB that has 8 recruiting classes represented on its roster.
Also, BYU might be the only team with players from the 2010 recruiting class listed as freshmen still.
Speaking of the 2010 class, it is the only year that is represented across all four classes.
You can see that they loaded up for this season: heavy on seniors and juniors with lots of transfers - particularly in the two-deep.
