I would prefer to get a guy who is opportunistic with turnovers and has size to start. Kelvin Hayden must be a fairly good tackler or else he wouldn't have been a starter for all those great Colts teams from back several years ago. I wouldn't be shocked either way with who would be the starter between Jennings and Hayden. They both have their strengths and weaknesses. The thing that bugs me, though, about Jennings is that Aaron Rodgers picks on him and makes him look like shit all the time. I can't say for sure how many times I've seen that Sheep Fucker up in Green Bay do something on the left side of the field because Jennings is too small to cover either Jordy Nelson or whomever else they have coming down the field that way.
In todays NFL being named a starter in most cases is only a pride thing. With the way teams rotate players as a starter you could have less playing time then your backups.
