I find most monikers cringy at best or downright embarrassing at worst but I can put up with them for marketing reasons, drawing in kids etc.
I generally think they’re done tastefully in rugby league but my main gripes are when the badge looks like some kind of clipart used by an 11 year old (Rochdale Hornets, old Keighley Cougars etc but there are far worse examples abroad) or the americanised over use where you have grown men running around shouting “go wolfpack” or “go dolphins”.
Castleford Tigers, Warrington Wolves etc do well with their branding but personally I prefer the more traditional names.
