perhaps it's a hint at their spots on the football depth chart
Maybe they will only be used if more than 2 players foul out? Porter and Jace P could come off the bench before they would need to use Vedral or Brant. But Vedral is a heck of an athlete....who knows....may be able to contribute alot with his quickness
They are suit fillers. Fred will play his seven scholarship players and will only play the football players if he has only four scholarship players left at some time in the game due to injury or fouls. He has two freshmen walkons he wants to red shirt that will travel, but does not want to play. This isn't like football where a red shirt can play in any games and still retain the red shirt.
