[Strikeout King]

If a game is way out of reach most teams put in their JV and let them play the rest of the game out, even with a minute or less to go JV will run plays to get the varsity experience but if a team leaves their starting varsity in a game that's well over with and it's the winning team and they score another TD then yes that's running up the score. I would say he's just letting his JV players getting varsity experience for the upcoming years.
