It's Aaron Rouse.
Anyway, I don't know if I would want Martin (Or Underwood, for that matter) out there at safety. We have, what I think, is a tweener already in Collins. I'd like to have a solid guy. More of a LB/S tweener than a CB/S one. Both Martin and Underwood are more corners than anything else, if you ask me.
Therefore, I think that Rouse might be the best option at this point. I hope that he has been coached up a little and won't be going for the big play time after time again. Otherwise I'd nearly put Chillar back there, weird as it sounds.
