Here's Matt Williamson's take on the trade, he's from Scouts Inc:
What Redskins get with Donovan McNabb - NFC East Blog - ESPN
I'm a big fan of Matt Williamson, and I feel like a guy like this has a bit more credibility since he watches tape and was an NFL scout, and is probably not out there to try to sell a story like Mosely or any other pundit (SS can correct me if I'm wrong).
That being said, I like his let's wait and see attitude. and I do hope he's right that a Buffalo or Oakland would send their second rounder for Campbell.
