I believe that there's going to be two open seats at Hendrick after this season. Kahne is a free agent. Correct me if I'm wrong.
Larson makes a lot of sense, but he's got the ball rolling finally at EGR, so I doubt he makes the move.
Keselowski, McMurray, Kenseth, and Stenhouse will be the biggest free agents. The only ones that I see feasible to make a move would be McMurray and Stenhouse. Not a lot to pick from this upcoming free agent class.
