is there any extra progress made for the players between the day the season ends, and the day the next season starts?? for instance, does a player automatically get 10points better from one season to the next?

Yes players improve in the offseason. Its kind of random and dependent on their WE

Yes, players do practice in the off-season and improve in some categories. Players with a better work ethic gain a little more in the off-season, while players with really low work ethic may lose points. Even some players with decent work ethic may lose a point or two in a couple categories. Seems to happen most often with stamina in my experience. 

i call it off-season improvement day.  It's like HD Christmas.  You wake up and your players are suddenly better.

There's nothing else quite like it

It happens the day the season rolls over. You know its time to check up on your players when you see the NBA draft email.

Also players can lose points if their WE is low enough. Sitting on the couch eating chips isnt going to help a player get better.

I can never remember what they looked like before the rollover, so for me its more like St Patrick's Day - you know something happened, you're just not sure exactly what...
