I do not think that any one position is done the most.  It is the position that will grow the most and do the most good from RS.

The results thus far appear to be showing what we all know...QBs are extremely important and they also tend to be fairly low rated (as compared to other positions).  This creates a need and desire to put RS on these guys to groom them for the future.

Interestingly, it also seems to show a bit of the "opposite"....in that RBs are typically the highest rated players (compared to other positions) and by putting a RS on them, it tends to create total "studs" that can take over the game and dominate.

Very interesting poll

Disagree fermor. The majority of coaches will emphasize QB and RB over other positions.
