And even if we sent both WR and TE's out, both backs are in to help block. Or Keep a TE and send an RB. Many ways to use it and we have a damn FB on the roster, use him.
I will add one counter to that, and then kind of kill my own argument. John Elway, the closest comp for Allen, went to 3 Super bowls and lost with going wide open (remember the 3 amigos?). Once Shanahan got there and they ran the ball with Davis, used a FB and got the TE (Sharpe) more involved, he wins 2.
That said... We aren't running a WCO (Which I advocated for 2 off-season's in a row) and we sure as hell dont have T. Davis in the back field and Mike Shanahan calling the plays. But you get my point.
