Buffalo Rumblings: That would definitely be middle linebacker. As maligned as London Fletcher-Baker was for being the middle linebacker on a pretty bad run defense, it's going to be difficult to replace his leadership and his playmaking ability. The inside position is perhaps the most important position in a Cover-2 defense (see Brian Urlacher in Chicago), so it's imperative that the Bills are above average at the position. Hence the drafting of Paul Posluszny - he's a bigger, stronger version of Fletcher with potential in pass coverage.

But throughout the off-season, the Bills have maintained that second-year man John DiGiorgio (an undrafted rookie out of Saginaw Valley State in 2006) was first on the depth chart. That continued through the beginning of the team's training camp, with DiGiorgio receiving the majority of first-team reps. DiGiorgio was very impressive throughout spring practices, showing a flair for the big play - but is it really feasible for an undrafted free agent to beat out a Penn State linebacking legend? Buffalo's coaching staff seems to think so. This one bears watching, and it's a battle that will probably go right down to the wire.

In the end, it's hard to imagine a scenario where Posluszny doesn't beat out DiGiorgio for the starting spot. His potential is too great to ignore, and he needs to establish himself as a stalwart in this scheme early. It's a virtual certainty that he wins the job; but every time I convince myself of that, DiGiorgio makes another play...
