PITTSFORD, N.Y. -- The Buffalo Bills have finished their second day of training camp, already completing their two-a-day portion. There will be single sessions and walkthroughs henceforth at St. John Fisher College.
Monday morning's workout will be their first in full pads. Plenty of kapows should resound.
"The intensity picks up a little bit," Buffalo receiver Lee Evans said. "When you have pads on the intensity picks up. It's easy to run around here with no pads on, but when the pads come on it's a different ball game."
Until then, here are a few observations and updates from the weekend:
Second-year right cornerback Leodis McKelvin should have stayed in bed Sunday. Evans and Terrell Owens abused last year's 11th overall draft pick in both sessions.
In the morning, Owens torched him twice and Evans once on long, arcing Trent Edwards bombs. In the afternoon, Evans made a sensational grab near the end zone on another long ball despite coverage from McKelvin and safety Donte Whitner. Not long after, Owens caught a quick in and then cut back to the sideline, sending the helpless McKelvin sliding on his rump.
At least McKelvin was getting beaten by some of the best in the business. Then again, he'll have to defend similar players during the season.
Sophomore tackle Demetrius Bell, who has been the second-team left tackle, took some first-team reps at left guard Sunday.
Marcus Stroud revealed he has been limited because he tweaked a hamstring Saturday. He called the injury "minor."
Langston Walker, after years as a right tackle, on learning the left side now that Pro Bowler Jason Peters is gone: "I'm a prideful person, and it is a challenge. And I'm sure there are a lot of detractors out there, but I'm here to prove them wrong."
Neither loss is substantial, but the Bills have suffered a pair of season-ending injuries already.
Linebacker John DiGiorgio was waived because he failed his physical after right knee surgery.
Running back Justise Hairston somehow suffered a season-ending knee injury during a walkthrough drill. Hairston was a long shot to make the team, but the New England Patriots' sixth-round draft pick in 2007 was a neat story, making the Bills camp roster through a group tryout after spending last year out of football.
Edwards on optimizing the no-huddle offense: "The hard thing about that is to make sure the defense doesn't get into a routine and understanding their calls -- making sure you're changing some things up, making sure you're putting in some double moves. You're putting in some dummy calls in there, too. ... It's pretty easy for a defense to pick up on some calls. So that's something that we're working on every day, and I feel like we're progressing pretty well on that."
