I think this is almost what happened. I think after the game the Bears were so impressed with AJM that they offered a package of 2 first rounders, a 3rd and the rights to the ghost of Urlacher (who is still alive). However, Beane saw the chance to mess with EJ Manual one more time, told McD "hold my beer" and moved McCarron to the Raiders. Once the Raiders got AJM, Mack became expendable. No,need for a pass rush when you have "Mr. Comeback". So, not wanting to come away empty handed, the Bears offered pretty much the same package for Mack.
