Cordy Glenn doesn’t see the point in spending a whole lot of time focusing on matters beyond his control. Whether it’s being at left or right offensive tackle for the Buffalo Bills or his ability to maintain his starting job, Glenn chooses to avoid assumptions and live in the moment. Coach Rex Ryan might be saying that Glenn is likely to remain at left tackle, where Glenn has been a regular starter for the Bills since they made him a second-round draft pick from Georgia in 2012. But Glenn knows that he spent much of the offseason practices alternating between left and right tackle with Seantrel Henderson, who started all of last season on the right side. “You’re a player, you just need to go out there and play,” Glenn said. “It’s like, ‘OK, this is where I’m at today.’ ” He was at left tackle for all three of the Bills’ mandatory minicamp workouts, the final set of group sessions until training camp begins on July 31. However, there is reason to believe some of that had to do with Henderson’s sudden demotion to third string after he failed to arrive for the first practice on June 16 due to a missed flight. “The way I look at it, when you’re here, you’re trying to help out your team,” Glenn said. “That’s the bottom line, really, trying to win. Anything you’ve got to do to win, you’ve got to do it.” So he alternated, even though the right side wasn’t as comfortable to him as the left because of the need to “get your muscle memory on the other side.” The Bills had solid reasons for the flip-flopping routine. They mainly wanted to see how well Henderson, who is entering his second season and offers the greatest upside of any of their linemen because of his remarkable combination of considerable size and athleticism, would apply his physical gifts taking on the more elite pass rushers that left tackles generally face. In a Bills practice, that’s a heavy dose of Jerry Hughes, among the better pass rushers in the NFL, among multiple dominant players they have up front. - See more at: http://bills.buffalonews.com/2015/0...he-flow-as-bills-tinker-with-tackle-position/
