You must remember there were a lot of QLD players that were unavailable for this series that would have added a bit of size out wide. The likes of Tonga, Tate - Hodges will more than likely have a look in next year if he keeps his form up. There are also a couple of young blokes playing down in victoria who are promising bigger players Ignis and Webster that are also QLDers. Add that to the current options of Sing, Berrigan, Bowman, Williams, Slater, Bowen, Schifcofske, Mogg, Frawley, Hannay and I've probably missed a few that is a fair selection of players a lot of them strong defenders.
Also to reply to what someone else had mentioned, out of the 15 players I have named there only 3 play for the Broncos, hardley a monopoly.
