While what you say is true, I believe that in BYU's case veterans like Hall, Saunders, Knell, and Fouss will help BYU defy those predictions.

Yes, BYU has a lot of raw, very talented, new additions to the team, and it will take some time to gel and get everything running smoothly. However, the veterans will bring a good dose of stability that will help to minimize the adverse effects of adding in the new players.
