Gonna need you to find snap count data to back that up. Ealy may have been a second rounder, but he didn't see significant time until nearer to the end of last year. Additionally, your 'production' only accounts for sacks and would require a split between run downs and passing downs to properly assess. Finally, you mention 'fighting their way up the depth chart' but this isn't college - you're either the starter, a backup/ST, or you don't see the field.
The 'Wofford conspiracy' is hilarious, as Jerry had almost 20 years prior to Bersin and never felt the need to sign a Wofford player. Bersin is on the roster because he can play in the NFL, even if only for a relatively talent-strapped team like Carolina. As far as making the opening 53, Bersin and Cotchery occupy a very similar niche and Cotchery's experience gave him the edge. Once Cotchery got hurt, Bersin was called up. Logical. As far as your points about Clausen and Bell, it's really not a player's fault if they're expected to do something they simply can't - the blame falls squarely on those who built the roster and those who put them in that position at all. Salary cap is a consideration, but Bell and Clausen are not quality starters and it is not surprising that true NFL talent makes them look bad. This is why Carolina didn't re-sign them, as replacing poor-performing players with better ones (in this case bringing Ginn back to return punts) is what good teams do.
This is correct. Inside of 2 mminutes a fumble can only be advanced if recovered by the player who fumbled. Even if the ball gets knocked 20 yards downfield, if the fumbling team recovers it returns to the spot of the fumble if the clock is inside of the 2-minute warning.
