Similar to what Ubiond said (rookie of the year award), I believe adding more awards (similar to NBA awards) beyond MVP would be a great feature. Below I breakdown how this could be measured:
Rookie of the Year: Similar to MVP measuring, but apply to rookies (I think this should be pretty straightforward).
Defensive Player of the Year: Takes into consideration steals, blocks, and overall defensive impact.
Sixth Man Award: Best player who doesn't start (can't start more than a couple of games).
All Team Awards: Similar to all star teams, but in three tiers.
All Defensive Team Awards: Best Defensive players (steals, blocks, impact) also in three tiers.
All Rookie Team Awards: Top Rookies in two tiers.
Thank you,
