Free agent receiver Vincent Jackson will generate heavy interest if he makes it to the March 13 market. The Chicago Bears are expected to be in hot pursuit, and the Union-Tribune San Diego expects the Buffalo Bills to be, too.

Kevin Acee of the Union-Trib reports that “it is believed” the Bills have interest in Jackson even after Monday’s five-year, $36.25 million Stevie Johnson deal. Buffalo is oozing in cap space after a rollover from last year, and it sounds like G.M. Buddy Nix is ready and willing to spend.

It’s worth noting that Nix was the assistant general manager in San Diego when Jackson was drafted. Working as G.M. A.J. Smith’s right-hand man, Nix oversaw the Chargers’ college scouting department.

Whether Jackson makes it to March 13 unsigned is unclear and perhaps unpredictable. The Chargers want him back, and he wants to be a Charger, but Jackson might be able to make significantly more money if he plays the market right.
