Why Can't the Steelers develop and plug in players like the Patriots do???

Seems like no matter who the Pats put on the field they can still win.
Doesn't matter how many times they've been cut, where they were drafted......they just win.

Rob Nincovich??? Drated in the 5th, cut by the Saints....goes to Dolphins, then back to Saints. Now he's all over the field with the Patriots!!
