Interesting top post. Good follow-up thread of posts.
It will NOT happen.
Not because I agree or disagree with ANY of the arguments presented in any of the posts above. I do not think that it CAN happen this season because our system and playbook is already in place in a completely different manner. Nor do I feel that it may happen in the future.

ey will not move to become a traditional TE. He is a HB and plays great as such, perhaps not as great a blocker as we had in the past (and getting better at it every season) but he may become one of the best HB at catching the ball in our history.
Our system needs far more urgently a RELIABLE and EFFECTIVE second receiver. We have not had production at all from that position. Patten was pushed around too much by single athletic coverage and my boy Taylor Jacobs has not proven himself yet (unfortunately).
I would argue this proposal differently with a question starting with the fundamental premise of the first post in this thread:
Is the Skins offense in the future, let alone at this stage of the season, better off trying to accommodate a new blocking system based on a traditional full-back blocking from the backfield rather than keeping the same Joe Gibbs system with a REAL threat with a reliable, effective and productive second receiver?
To me, the ansswer is obvious. In the best fantasy scenarios, I would rather have not one but two Santana Moss running around downfield than a full-back in the back TO MAKE OUR RUNNING GAME BETTER.
To run well, a defense must feel threatened by more than one WR and a HB or TE. It needs to feel the urgency of not knowing whom to double cover downfield. That was the beauty of the Monk-Clarke tandem. One hurt you, the other finished you up. As a result the running was better having a HB (bigger than most FBs) paving the way for our RB.
When well executed with the right personnel, our system is BETTER than Denvers's system.
My argument is that we have a personnel problem at the 2nd spot, not a system problem. How do you like that?
Interesting and provoking thought by the Hogstera and others though. I will give you great credit.
Daniel Snyder has defined incompetence, failure and greed to true Washington Redskins fans for over a decade and a half. Stay away from football operations !!!
