I wouldn't be opposed to expanding a bit, but I think more than 14 teams would be a stretch unless we reduce the number of players on each squad. 14 teams might even be to many with 13 position players per team.
Also what about adding another DL slot (or two)?
If we get more than 12, I'd rather see having people wait in reserve (cut owners that are inactive for a month) or joint owners.
As for the DL, Thadeus has already added one (so we have 2 now). I think two spots are fine. I want it be a tough decision to keep players that have long term injuries, but I won't stand in the way of increasing it to 3.
EDIT:
Do I have to be invited to the league or am I missing a 'join' button somewhere?
You'll need an invite from our beloved commish.
