These are the current Vegas odds on the 2017 Super Bowl.
SEAHAWKS 8-1 Don't need an RB
PATRIOTS 8-1 : Desperately need a RB and he fits perfect into the system.
STEELERS 8-1 : Bell will be back, short on cap space.
PACKERS 10-1 : Lacy should be back, they rarely bring in FA players.
CARDINALS 10-1 : They have David Johnson and a few other young players. Might resign CJ2K also.
BENGALS 12-1 : They have two young RB's No need.
COWBOYS 14-1 : Now this is one of the few teams that is a possibility. But CMON, the cowboys?!? ha
PANTHERS 12-1 : Again, they are ok at the position and have many upcoming contracts to deal with.
BRONCOS 20-1 : The still have decent depth at the position. Wont be much of a contender with no QB
VIKINGS 20-1 : AP
COLTS 20-1 : Now this is another possibility, however he did say "contender" Right!?!?!?!
CHIEFS 20-1 They have Charles and more then enough depth.
FALCONS 40-1 Freeman should improve and they have other young talent. Also have other priorities.
JETS 30-1 : They'll resign players before they bring him in.
BILLS 30-1 They don't need him.
Honestly, if he really wants to play for a contender and contribute, New England is the only place he should consider. The Cowboys would be the only other realistic option, but if it's really about "superbowls" then realistically the difference in likelihood of that happening, is much greater with New England.
If he'd be willing to come for 2 million a year, with the possibility of it being 3 million with escalators, that would be a wonderful steal and FA signing. Him paired with Deion Lewis would make an awesome starting duo. James white, and hopefully a healthy Tyler Gaffney could play backup to both respectfully. Take a RB in the later rounds or look for a UDFA. Think Thomas Rwals.
