I can garantee you that as far as i am aware and in my time with the roos we have never played a player from another leauge under a bogy name like coota did round 1.Tez, are you saying that the mighty Yass Roos or any other club for that matter have not done the same thing at times??
We did in my time play Ben serafin as ben serafin against Belconnen when he was playing for and registerd to Ainslie a few years ago so we could take the feild with 14 players.
And while i cant speak for other clubs i would very much doubt that any club would play 5 players while unregisterd.
Mcgowan,Vitnell,Warner,Corby,Forsyth.
