What has Shanny done that makes you think he can suddenly pull this off? Has he yet to do this? Last I saw he hasn't done anything since Elway left, his prized running game failed in Denver, his OC came here, and oh yeah he got fired.
You're correct, good teams hit on talent in lots of different ways. Washington is not one. They've been successful on their 1st rounds picks and that's it. Don't believe me? Look for yourself:

FA has been a disaster and that's putting it lightly.
So where does that leave them? In last place in their division, with a rookie QB w/o offensive weapons, an OL, or draft picks with a front office that manages to shoot themselves in the FACE all the time. On the bright side their D is decent sometimes.
