That's been talked about quite a bit around here and I do think that Parcells follows that theory pretty closely. Peterman definately needs to show something... and I think he has the ability to do it.
Now, does Parcells look at the "Three Year Rule" as having any footnotes, like an injury? With Peterman missing his whole rookie year will Bill allow for that and give him a fourth year? I don't know, but I think Peterman needs to show significant improvement, even if he doesn't "arrive" like Bradie James did last year. With no growth, I think Peterman will be gone... however, I think he will do well this year and either be a starter or a primary backup and swingman. I kind of think he's a darkhorse candidate to fill Larry Allen's shoes. I feel like Parcells knows Steven will pley pretty good this year and by getting Kosier that he leaves a door open for Peterman to win the job.
In other words... Had we gotten someone like Steve Hutchinson, then Peterman definately would've been a backup... but with Kosier, Peterman could play well enough to win the job. At the very worst, if Peterman doesn't come around, we'll have a solid starter in Kosier. At best, Peterman beats Kosier out of the job, which would mean that Peterman has turned out to be a good G.
