Max 14 Imports, max 5 Brits over 23, as many Brits U23 to make 22 on game day bench.
If you have 11 imports then you could have 6 U23 Brits
If you have 3 Brits over 23, 12 imports, then you could have 7 U23 Brits
Not sure but I think you can only dress 2 Netminders on game day. If both are injured during the game then one of the other players can put the pads on and go in goal. Not sure though
