I'm worried. Bush isnt a true #1 RB, and I'm not sold on Thomas. While RB's may make the easiest transition into the NFL, there are plenty of successful college backs who are unsuccessful in the NFL. Ronnie Brown, Karim Abdul-Jabbar, Sammie Smith, Lorenzo Booker, J.J. Johnson, John Avery. Busts.
What's this word "true" always used for. A "true" #1 receiver, a "true" #1 running back, a "true" fan. Bush is fine. If New Orleans used him that way, you would not say this, I think that is true.
