Attribute Rollback
Each season, players lose a percentage of their attributes from the prior season (call it offseason rust). The percentage that players will retain (maximum of 50%) is based on how many full seasons they participated in. The formula is such:
Base Stat + Ending Stat * (.25 + (.05 * (Number of Seasons Played - 1))) + Awards and Bonuses earned from all seasons
Again, the "Ending Stat" in the middle is rounded DOWN once all calculations are performed.
EXAMPLE:
Ham Burglar - 5'11" G
Speed Base = 24
Ended Season 2 at 120 Speed = 120 * (.25 + (.05 * (2 Seasons Played - 1))) = 120 * .3 = 36
Season 2 Playoffs MVP = +1 Speed
This formula applies to all stats BUT Endurance. ENDURANCE IS RESET TO 10 AT THE START OF EVERY NEW SEASON!
Therefore, Ham Burglar would start Season 3 with 24 + 36 + 1 = 61 Speed. His training time would be normal as if he had already trained to 61 speed (around 2 hours per point or so), but he gains all those training credits to spend elsewhere.
