Reason I asked about the LB corps is because I really don't have a good clue about how they have developed since being drafted. I'm familiar with the names as draft prospects, but haven't watched them enough to know if they've surpassed their draft values. I know Gocong was a sleeper that Philly took a little to early to now call him a sleeper and I liked Bradley as one of those gritty hard working types with limited upside, but didn't know how far he's come. I think Gaither improved a lot last season and I think he'll get even better this season if he can get to the QB and cause more turnovers. I know nothing of the backups though.
While I disagree with BBD that they are a better group than the Cowboys LBs as a whole, I do agree with him that it's not really a fair comparison considering the difference in schemes.
As for Philly's D being better than Dallas' D, there is a strong case there, but I usually tend to think Dallas gets overly criticized because of Roy Williams. I don't really care to debate the issue since the season is about to reveal it to us soon enough.
