Just an FYI, apparently I was wrong about taxi squad being automatically kept, so I will be increasing keeper spots to 40 to accommodate this. You may keep up to that many players. However, you will need to cut at least five of them before the draft begins if you want any draft picks. Once the draft is over, each team will be required to remove any non-rookies from their taxi squad and replace them with up to five rookies, so you will need to cut at least five players at some point.
Also, to clarify any confusion, the five open roster spots for draft picks must be open on your main roster, not your taxi squad. Picks won't automatically draft into the taxi squad, so move five of your keepers to your taxi squad to open up the necessary roster space and then swap them out with rookies after the draft.
I'll be sending out an email to the league about this tomorrow or Tuesday.
