According to the report, Franklin has told people that he will leave the Denver Broncos, where he has spent his four NFL seasons. Franklin has started each of the 63 games he has appeared in during his career since being drafted in the second round of the 2011 NFL draft.
Pro Football Focus ranked Franklin second in the league among guards in Pass Block Efficiency last season, but he was flagged 10 times in 2014, third-most at his position.
During Franklin’s first three seasons he played right tackle, but he exclusively played left guard last season.
The Broncos are about $19 million under the salary cap after using the franchise tag on wide receiver Demaryius Thomas.
