I would imagine that a team could get sponsorships from companies (other collegiate sports do it). I don't how many players would go for it though. Most players are already set with their racquets before they go to college. My coach would give us contacts for companies that would give us discounts on racquets and gear while we were playing. (The discounts ranged from about 30-50%)
