(Continuing a monthlong series analyzing players who are on the roster bubble and where they potentially fit in 2014.)
Name: Seantrel Henderson
Position: Offensive tackle
2013 stats: 12 games (eight starts) -- at Miami
Chance of making 53-man roster: 55 percent
Why he should make it: They don't make them much bigger than Henderson, who at 6-foot-7 and 331 pounds is one of the largest players in the NFL. He began OTAs at third-team left tackle but saw reps with the first team when Cordy Glenn was out with an illness. Does that signal he was progressing well this spring? Perhaps, but it could have just been Doug Marrone wanting to see what the seventh-round pick could do with the top unit. Ultimately, it's that hope that could keep Henderson on the roster. Cutting ties with 32-year old right tackle Erik Pears would open the door for Cyrus Kouandjio or Chris Hairston to step in at right tackle and likely assure Henderson a spot on the 53-man roster.
Why he shouldn't make it: Henderson was the third and final offensive lineman the Bills drafted in May, which could hurt his chances of making the team. He could come along nicely this summer and still lose out in a numbers game. If the Bills keep Glenn and Pears as their starters at tackle, with Kouandjio as the top reserve, there might not be a spot for Henderson. He would need to pass through waivers before joining the practice squad, but that might be the best spot for him this season.
