There are a lot of wacky things going on around the game right now, with the shifting rules on roster sizes being a prime example. At the outset of the season, teams were permitted to carry 30 active players. The original plan was as follows: two weeks into the season, rosters were to go from 30 to 28 and two weeks after that, from 28 to 26.
That is no longer the case. Now, teams have to reduce their roster size to 28 today, and that number will remain in effect for the rest of the season and postseason.
