So I had a look at the draft class which I downloaded and apparently the amount of players is only 168, was just wondering if there are any more prospects forthcoming considering the league requires over 210 players for a draft.

The draft class in the new UI is borked.

So there are lots of bugs within the new UI I think that is well documented, do you guys think it would be better to slow down offseason to try to have as many bug fixes happen as possible or should we still go full speed through the 2012 offseason into the regular season?

Yes.
please.
I suggest:
after champ/before efa 1.
before draft.
after draft/before lfa1.
after lfa1/before TC.
after mid pre wk 1.
before reg wk 1.
