The linebacker corps is the weak link on the Miami Dolphins defense. That means there are opportunities, and rookie Jordan Tripp is doing his best to show he can be part of the solution to stabilizing the unit. The Dolphins didn't address the position in the recent draft until the fifth round when they selected the former captain of the Montana defense. Tripp is already being touted as a value pick who will outperform his draft position. During Thursday's practice, Tripp got extensive work with the first unit and also in the nickel package. Though projected more as an outside backer, he is also getting a look in the middle. "It's a broad spectrum. The more knowledge you can bring to the game the more reliable you're going to be," Tripp said. "My comfort level is only getting better and better. I'm just taking advantage of the reps they give me and focus on making new mistakes, not the same ones again, and learning from those mistakes."
