Disagree...Wilkerson was here last year and is playing well. Babrer has been here for years and is playing reasonably well. Lefty was not here last year and stunk it up. Caddy has been here awhile and is playing reasonably well. Penn was here last year and playing well. So your comment "The players brought in that were not with the team last year are performing while the leftovers see that their time is ending" is not altogether accurate.
Wilkerson showed up for one game that's like saying Adams or Clayton is playing well. That whole DL is pretty consistently stinking up the joint.
The only guys right now that are playing well for the year (as opposed to showing up for a game here and there) are K2, Barber and Hayes. Other than that we've got a raftload of inconsistency from guys who can show up and then vanish (Clayton, Wilkerson, Adams, Talib, Caddy, Ward, Davin).
