As I said below, nearly year with Brown, Unga, and Williams automatically makes the cut. That alone is almost a decade's worth. But we're talking since 1997, so 1998 is one of them. Easily better.
Then you have 2001.
2000 would have been if they could have stayed on the field.
02 with Whalen and Brown was arguably better looking than this so far.
So, 98, 2001, 02, 05, 06, 07, 08, 09, 10, 13, 14, 15, 16.
I get what you're saying, but let's not act like BYU rarely has good RB groups. Someone on CB tried once says that BYU isn't known for RBs, but frankly they have been. They're not all superstar NFL draft picks, but BYU has a long history of good RB play. Far more often than not.
