So I am new player and I am looking for some information on roster size. Can someone tell me the roster sizes that we are allowed to maintain?

I was able to find the roster limit of 60.

60 is the roster number up until the end of pre season. You can have all 60 players active then as well.

The roster limit in the regular season is 53. You can have 46 active for each game.

Thank you....that changes up my plan then
