Colin Brown's grasp on a starting job with the Buffalo Bills could be tenuous.
Brown has struggled in the Bills' first three games -- and that's putting it nicely.
The website Pro Football Focus, which grades every play of every NFL game, has Brown graded as the worst starting guard in all of the NFL. Brown's pass blocking efficiency, which is a metric used by PFF, is 89.1 and he's accounted for 18 of the offensive line's 35 pressures allowed, according to the site.
Since PFF started handing out grades in 2008, Brown's cumulative season grade is the second-worst ever recorded.
With a matchup against hulking Ravens defensive tackle Haloti Ngata on tap Sunday, Brown's performance will again be in the spotlight. The matchup will take on even more significance for Brown because the player he was competing with for the starting left guard job during training camp, Doug Legursky, is probable to play Sunday as he nears his return from a knee injury that has kept him out the first three weeks of the season.
Another poor performance from Brown could result in a change to Legursky along the Bills' offensive line. Ngata, 29, is 6-foot-3, 340-pounder in his eighth NFL season. He's a rock in the middle of the Ravens' defensive line, and will require a double team by the Bills on most plays (with Brown being joined by center Eric Wood).
