1) Look for Hill's completion % to get up to about 63% or better.
2) O-line play. They need a great deal of improvement over the last few seasons. If They are protecting Hill and opening holes for the RB's early in the season, then it's going to be a good season.
3) Performance of the new big receivers -- Leslie, Blackmon, Kurtz. Looking for one or two to fill in the gap left by Hoffman's graduation.
4) DB play. If they play at least as well as last season then it should be a decent season for the D.
No one really seems to know exactly what the violations were but it seems fairly sure that there will be some suspensions to start the season. Just hope that it isn't too many or one or more of the key players.
