The comps with Ryan Tannehill do have merit in a circumstance sense but he was a competent starter before he thrived in Tennessee though. It wasn't his decision making that was in question. His qb rating the last 6 seasons has never dipped below 88 and has been as high as 117. He took the leap from average to borderline elite with the help of a quality roster and the biggest running back in the league. The difference is they have a line to protect him while Carolina has a void at Sam's blindside until proven otherwise. Teams like Tampa will be chomping at the bit to put that to the test.
