There's a report on PFT that links to a story by Bob McGinn of the Milwaukee-Wisconsin Journal Sentinel. It looks as though Green Bay is going to be parting ways with Jermichael Finley during the offseason. Apparently, Finley isn't living up to the short term deal that he signed. The Packers are going to owe him a $3 million roster bonus, $4.5 million salary, and about $1.5 million in other bonuses.
The Bills, meanwhile, seem set to pay Jackson a little less than $4 million. Given the need to clear some cap space the Bills might need to convince some veterans (ahem, Kelsay) to give up some of the money they're set to earn in 2013. Jackson doesn't strike me as the sort to walk away from his only lucrative contract. It's not that I think he's selfish; he toiled long and hard for his deal and I can see him not wanting to let the Bills back out. The front office, if forced to choose between re-signing starters like Levitre or keep a backup like Jackson, well, that's no choice at all.
Trading Jackson to Green Bay for Finley allows each team to divest itself of a player who has contributed in the past but who also had a down year in 2012. The Packers need an upgrade at RB and Jackson could fill that need for the next couple of years and help keep Green Bay in contention. Meanwhile, Finley would bring a new dimension to the Bills' offense. Chandler has done better than any other Bills TE this century he's not exactly an elite level talent.
Each man would have to restructure his deal. I can see Jackson accepting it a bit easier than Finley. After all, Jackson would finally get to play for a good team while Finley would be shuffling off to Buffalo...
