I can include temp; that's not a problem. Temp for all players.
Perverse, I'll try to work out some way to incorporate GK.
I'm hesitant to up weight or down weight the actual stats according to position. It will see us play players out of their actual positions more, I think.
More that we'll find ways to cheat the cap i.e. simply hire wingers to play the backline due to them being cheaper but as effective as a FB and centre.
