I didn't mean to have my whole post in response to yours, sorry if it came off that way. You didn't have to repeat yourself; I think we agreed for the most part.
To continue with my role as Captain Obvious:
Theoretically, as silly as it sounds, five plays a game could have an impact on a man's season or career, though. It adds up to 80 possibly punishing plays over a 16 game span. Obviously we see snap counts considered more with RBs (Andre Ellington, for example), but minimizing a players' snap-count has long been thought to be a way to prolong a players' prime, regardless of position. Less constant wear and tear and less chance of traumatic injury = better durability.
Not much too argue, IMO.
