Whispers from around the NFL

• RB Willis McGahee wouldn't reveal his weight, but he looked noticeably slimmer and more toned at the Bills' June minicamp than he was at the end of last season. Word is McGahee believes that carrying less weight will bring back some of the explosiveness he lacked last season.

• Sources close to the Raiders indicate that WR Jerry Porter isn't the happiest camper with the way new head coach Art Shell has pushed for more discipline. Sources cite the sometimes tenuous relationship Porter had with Jon Gruden, who, like Shell, was more heavy-handed than Bill Callahan or Norv Turner. The Raiders have dangled Porter as trade bait in the past, so it wouldn't come as a complete surprise for Oakland to shop him if things don't go well early on.

• Sources say Broncos QB Jake Plummer has been sharp throughout summer workouts and appears to be as confident as ever despite Jay Cutler looking over his shoulder. Though the real bullets have yet to start flying, we're hearing that Cutler looks like the real deal to this point.
