RBs have the must touches of the ball and thus have the most contact
you can older backs if they hadn’t been used much as backups. You drsfted st 24, first 2 yrs little play, thrn you play 25-28 similar to others who may be 21-24 yr olds.
RBs tired out after they pass Y touches st whatever sge it occurs.
WRs don’t take as much hard contact. They usually encounter DBs. It’s usually nota heavy hit.
