I have an idea: Give rewards such as 10 skill points to players who get 1st or 2nd best in Top Goalscorer, Top Rated or Top Passers.
Top Rated:
1st: 10 skill points
2nd: 5 skill points
Top Scorers:
1st: 10 rests
2nd: 5 rests
Top Passers:
1st: 10 treatments
2nd: 5 treatments
I think this is a useful way to get bonuses from ingame play.
