I'm a firm believer (after years of seeing the Saints learn the hard way) that it's not just about getting the biggest, best skill position players. The Rams will be good. I think we'd be naive to think otherwise, but that doesn't mean they are headed to the SB.
The Vikings, on paper, were simply much more talented than us last year (especially because of how many people we had on IR). Yet, it took the flukiest play in a decade to keep us from the NFCCG.
In the end, it's still about coaching, a great QB, good depth, and a good game plan more than whether you have Peters, Cooks, or Suh.
