A Unique Draft Strategy - Please Advise

I pick 3rd in a league where the QB gets 6 pts for passing TDs. Everything else pretty standard.

Right now, my plan is to pick up Peyton Manning with the 1st pick. With my 2nd pick (#21), I plan on picking up either a Tier #1 WR or, if none are available, the best running back on the board. Round #3 will be top running back if I choose WR in round #2, or either a RB or WR (best value) if I pick a RB in round 2.

My feeling is that if I can get Peyton and Moss, I can count on the 2nd level RBs being available in rounds 3, 4, and 5. Is this a recipe for disaster? I really believe NOT picking up Peyton at #3 would be a mistake given (i) our league rules, which are slightly unusual and (ii) the question marks surround Priest Holmes, who I would pick up if I didn't take Peyton (assuming Tomlinson and Alexander were gone).
