If its 40 players exactly, yay.
If > 40 players, await responses on thread from them. Responders get first billing on teams. If responders total say 20, the rest are drawn from lots.
If <40 players, fill empty slots with players who have only just returned after hiatus, eg Hawks got a few "returners" eg Chief.
If still <40 players, fill empty slots with 2nd-seasoners who hardly managed any games last season. Can use the stats I put in the "Season 13 Stats/Ladders" thread to calculate. Least games played equals highest chance to play.
Captains : let them vote on it. Coaches ... heh, you and me?
Simming? I can do it, but if you want to (and can?) then go for it.
