RB will get you on the field and then I would have to say along the D-line would be the next quickest and easiest. RB know the holes and just have to pick up on terminology while DT and DE know the gaps and need terminology down too. WR is another position that can get you immediate playing time.
QB,OL,LB,and DB must learn all of the complexities of coverages, blocking schemes, stunts,etc.;what to do if this or that happens changes thinking where RB and DL don't get into those concepts.
