Teams can negotiate with players from other teams at midnight, 3 days before they can officially sign them, never understood that.
So far I've read that Minnesota and Miami seem to be the leading candidates for Pittsburgh's Mike Wallace.
Dashon Goldson to either Philadelphia or Cincy and he's probably going to get Eric Weddle $$$$.
Guys like Andy Levitre, Andre Smith, and Paul Kruger are going to get $8 - $9M/yr.
Steven Jackson still wants to be a starter.
Greg Jennings wants $10-$12M/yr.
Teams with the most cap space are Cleveland, Miami, Indy, Cincy (aka the small market teams).
