Well, here's the thing....how many actual starters do they need? By my count: C, RB (sorta), S (If Smith retires and it's starting to sound like he isn't), FB, and DT.
That's not a heavy shopping list. So if you can fill in rotational level pieces in FA that makes some sense. Clear the books out from your mistakes and use FA money for rotational/depth guys. It makes sense, but just another symptom of the fail of last year.
