That's actually really foolish given the resources you need to devote to the position. You're no better for passing on the next Tom Brady than you are for passing on the next Antonio Gates, or more realistically, the kind of depth you need at positions like LB and OL to survive in the NFL. You build your team and there are usually only 3 quarterback slots at best, with only one of them on the field at any given time.
Every other year could make sense, especially given injuries, and I would probably not go longer than every 3.
