Besides Light (I wasn't here in 2001), where were "we" wrong about that group?
Actually there were many here that were looking for Matt Light's replacement several years before his retirement. Once an "expert" talked about Light's problems with the dreaded "speed rusher" and it quickly became clarion call phrase in many threads here looking for Matt Light's replacement.
Ironically, his final year here, might have been his best in handling those speed rushers. That might have been possible due to the fact he was lighter because of his illness, or the presence of Solder as the blocking TE on occasion. I don't know, but I'm going off track here.
I'm no sure what everyone's expectations of McClellin were. Given that our base defense has been a nickel for the last few years, and we've used essentially just 2 LB's on a regular basis, most of the time. AND Collins and Hightower are going to get the vast majority of those snaps. Did anyone think of McClellin as being anything more than LB/DE depth?
As for whether anyone was wrong about Edelman, Chung, and DA, yeah you were. Both Edelman and DA were being damned for being injured, which has nothing to do with the player's skills and potential, ALL of which have since proven those people wrong. And BB himself has taken the blame for Chung's first time with the Pats, and since he has been used better the 2nd time around, Chung has become one of the better 2 way safeties in the league.
There are a lot of reason a player make not succeed in this league. In an era where it seems we need immediate gratification, we seem less interested in a real progression of a player over time in this good system. For example, people would have thrown away Kevin Faulk because he was a fumbler, never considering that he MIGHT get better at that aspect of his game. I can recall Flemming getting run past way too often his rookie year and basically dismissed him as a potential OT. No one was running by him yesterday. Clearly he's gotten better. I did the same thing to James White, when it seemed that he got knocked down by first contact. Clearly this season, he's gotten better.
So I guess what I'm pointing out, is that I have no problem with people who criticize bad play of a player (when it's deserved, which is sometimes tough to determine). That is our job as fans. HOWEVER, where I have a problem is when a player gets beaten or makes a bad play or game or even year, that mistake is considered to be terminal and something they can never recover from.
THAT is the beauty of football. In THIS game, more than any other, coaching has the greatest impact on the play of their players. So even at the NFL level, players DO get better, IF they are getting good coaching.
