Where is the source for this? Or, is just your opinion? I know it was stated by DA/Loomis that he was not healing as fast, but thats a long way away from retirement.
Nick Underhill. Nick didn't say he's certain to retire. But he did say he has lost a lot of weight and he thinks it's likely he is going to retire and indicated that it seems like the only reason he isn't retiring this year is because he wants to help the team by waiting until next year when they can spread the cap hit of this retirement better.
