If we agree PF/C skills mean Rebounds, Inside defence, Inside scoring and Blocking.
Blocking: last in guards priority list of skills
Inside scoring: WEll, if u want your guard to score a lot, It might be useful
Inside defence: I dont think this is very important for guards
Rebounding: This depends on your team. If your forwards and centers are good rebounders, I wouldnt spend time to train this, but if your guard is tall he can get a few rebounds. I'd say this isnt useless skill for a guard.
