Coach Dick Jauron was in the midst of discussing the electric quality Terrell Owens' presence brings to the Buffalo Bills when, as if on cue, a roar of cheers and shrieks erupted from the other side of the field in Pittsford, N.Y.

The cause of the commotion was Owens, of course. To the delight of the hundreds of fans who had waited after practice, the star receiver elected to hold an impromptu autograph session that lasted nearly 25 minutes and thoroughly drowned out anything his coach had to say about the Bills opening training camp yesterday morning.

Not that it mattered to Jauron, who's quickly grown accustomed to being upstaged by Owens after spending most of his vacation this past month fielding questions about T.O.

"It adds a lot of excitement," Jauron said. "I don't know how [the attention] can be bad."

It wasn't at all bad on a muggy day in suburban Rochester, N.Y., for the Bills and their fans, who got a firsthand taste of T.O. mania. More than 5,000 fans combined to attend the team's two practice sessions, and a majority of them were clearly there to see Owens make his public practice debut in a Bills uniform since signing with the team in March.

Cleveland has signed center Alex Mack, the first-round draft pick from California. The All-American was awarded the Draddy Trophy in 2008, given to college football's top scholar-athlete and was a two-time Rimington Trophy finalist, given to the nation's top center. He did not allow any sacks or quarterback pressures on 397 pass plays as a senior in 2008.

With Brian Westbrook recovering from ankle surgery and a lot of inexperience behind the star running back, some might wonder if Philadelphia should sign one of the veteran backs still standing in the unemployment line, such as Warrick Dunn or Edgerrin James. The Eagles say no. That's good news for draft pick LeSean McCoy from Pitt. "We're a little inexperienced, but at this point at running back we think we have some real quality people there," Eagles president Joe Banner said this week.
