By the time the Bills take the field in Chicago to open the season, the offensive line could look vastly different than it did last year.
Head coach Doug Marrone has been working with a number of different offensive line groups throughout camp, and there's at least three starting jobs up for grabs. One is right guard, where Chris Hairston and Kraig Urbik were getting first-team reps.
In later practices, rookie Cyril Richardson got in the mix with some time with the first team. Urbik was the starter Sunday, and one could label him the leader of the pack if he starts the next preseason game as well.
Right tackle is another position that could go in a number of directions. Erik Pears and Cyrus Kouandjio have been the main competitors to start on the right side. Pears struggled in 2013, so the door is open for Kouandjio to take over. But Kouandjio has failed to make his mark yet in camp, and Pears was the starter against the Giants.
One bright spot so far has been seventh-round rookie Seantrel Henderson, who could turn into a steal for the Bills. Henderson started at left tackle for Cordy Glenn, and the rookie held his own. Henderson has also been having a solid camp, and according to Matthew Fairburn of Syracuse.com, he's been improving daily.
Assuming Glenn makes it back in time for the regular season, which Tim Graham of The Buffalo News expects, he will be the starting left tackle. But Henderson is still making a case for a roster spot and could even get in the mix at right tackle if and when Glenn returns.
