Here are some Whispers we've been hearing from our sources around the NFL:

• The Cowboys are said to be keeping their eyes open for receivers. The Dez Bryant incident had no effect on this; the team had planned to look for WR help before he was arrested. With the injury to Danny Coale — the fifth-round rookie suffered a stress fracture in his left foot in late May that required surgery — and no clear front-runner for the third WR position, it’s possible that the team will add help from the waiver wire at some point during the preseason or after. Remember, Laurent Robinson and his 11 TDs were added last season prior to Week Two. If the right vested veteran comes along, the Cowboys could make a similar move early this season.

• The Vikings have no need to rush RB Adrian Peterson back from injury, and if he has to miss a few games they feel good about Toby Gerhart entering the lineup. The fact that the offensive line could be improved in as many as three spots also gives the team comfort that there is absolutely no need to push Peterson to return faster than he needs to be.
