I guess technically speaking, Tigers and Dragons are new teams. But as far as I know, Dragons have long been an old boys club and the old boys might well have been very good players but aren't good administrators, coaches, talent scouts and etc. And their current coach has a very widely publicised issue with team selection. One has to give it to him for sticking to his guns on the issue.
I didn't know what was the problem with the Tigers until I read it here. Wests are paying all the money but most of the administrators are from the Tigers side. Not sure how they went so wrong on the field. Paying overs for duds. Though I think they might have gotten it right now and be a hard team to beat next year.
If or when both can get it right, in theory they'll both be powerhouses. But then again, Gold Coast should be a powerhouse as well. At least compared to Sharks, Rabbits, Roosters, Dogs to a lesser extent.
