But there's more... it looks like Whaley will remain as GM, but here's what he needs to replace wth upgrades.  As the current crop of positions I"m about to list aren't good enough: 
  
HC -- Rex clearly gone, that's fine.  I can't even imagine who I would want replacing him.   
  
QB -- I want to love TT, but he's clearly not playing anywhere near last year's level... pretty much all season 
WR (2) -- Woods, Goodwin and Harvin all probably gone.  Hunter and Lewis have had no impact, only Sammy remains if healthy 
RT -- We've talked about this all year 
  
DT -- Kyle Williams has to be near the end 
CB -- Gilmour gone and hasn't been that great all year, save a few INTs the last couple games, we can't possibly pay what he wants 
SS -- A. Williams will retire, Bills should force it if he doesn't want to.  We've struggled in the secondary throughout 
  
That's 6-7 new starters mostly at high skill slots... and again, the current crop, even if healthy wasn't getting it done
