Rivalries are definitely something that can change a lot over the years. For a long time Edmonton and Texas were probably the two teams I couldn't stand the most in the league, but that was long long ago, probably before most of you even joined the league, and even though I still haven't played for either team I don't mind them at all nowadays. Another team I really didn't like for quite some time was Buffalo, although that was built more on personal animosities than on the team and its players, and it's kinda tough to call this an actual rivalry as well given how much they have dominated both us and the league as a whole over the last decade or two. Kinda the same is true for the Hamilton Steelhawks who have rolled the league for much of the last year or two, but who I have a strong dislike for for there "fuck the league and everyone in it as long as it means that we win" attitude. But the one team I would call an actual rival nowadays is New Orleans. Sharing a conference, competitive and controversial playoff battles, cheating allegations, chirping and shit-talking around the boards, those are all great recipes for a rivalry and I would think the relationship between LA and NOLA over the last few seasons definitely qualifies as one.
