The Dolphins have given second-year quarterback Ryan Tannehill new weapons in Mike Wallace, Brandon Gibson and Dustin Keller and brought back Brian Hartline. In an interview with CBSSports.com, Hartline said Tannehill is poised to improve this season. "In this day and age, teams are typically defined by your quarterback," Hartline said. "His ceiling is as high as it can be. He’s taken the right steps this offseason through leadership and working with guys and getting better. As long as he continues that and continues what he’s doing I don’t have any hesitation with how good he’s going to be. Again the proof is in the pudding, but he’s a great guy and he wants to be great. That’s all you can ask for."
