Not since Jim Brown has a running back averaged over 10 yards a carry over the first two weeks of the season like C.J. Spiller, showing over the last two weeks (and the end of last season) why the Bills picked up the explosive back with their first pick in the 2010 draft. But what tends to get lost on Spiller's breakout performances is the improved play of the offensive line. Call it the Buffalo Bills secret weapon.

With the drafting of Cordy Glenn, the Bills filled the biggest piece of the puzzle, solidifying the coveted left tackle position. Adam Levitre and Eric Wood, two players picked up in the Marv Levy GM era, are still young players who can only get better, and Ken Urbik and Eric Pears fill out a nasty front five.

Glenn is the biggest surprise, transitioning nicely into a starting role in his first year and showing why the Bills thought he was a first-round pick who they were lucky to get in the second round. His ability to get out in space to block on the edges of the field, his footwork and wide body are proving to be just what the Bills needed. With the line looking like it is solidified, two great running backs and a vastly improved defensive line the Bills can only get better. Next year, Nix and company can work on filling out the wide receiver and linebacker positions and improving their depth. With the pick up of Glenn, the Bills no longer have to pass on skill positions in the draft. That need is filled for years to come.

The Buffalo Bills vaunted offense of the '90s was fueled by the play of Jim Ritcher, Will Wolford and Kent Hull. The line was filled out by players like John Fina, Glenn Parker and "The House" Howard Ballard. They were the engine that made Jim Kelly, Andre Reed and Thurman Thomas run. You can't help but to believe that this group is the best line since then and the play of Spiller (and Jackson) proves it. The Bills O-line has yet to give up a sack this season, and dating back to last year, they have shown that they can create holes for our talented group of running backs. Sure, C.J. Spiller is impressive, but without this much improved group, he would have never gotten to the second level of defenders where he is most dangerous.

This is how you build a football team, from the trenches out. As long as this group stays healthy and the defensive line lives up to the hype, the Buffalo Bills are on their way up.
