Do u like supporting the under dog? Do you hate it when everyone supports the most dominant fighter?

Some people love dominant fighters and support them religiously and if they lose they move onto the next best , this annoys me

To be honest, i can't clearly even define an underdog in combat sports because underdogs depend on the fight and the fighters at the time

The only real underdog i can think of in combat sports is dewey Cooper

What do u think?
Help define an underdog

and what do u do? support the best or the underdog?
In a fight, unless i like the fighter, i go for the "underdog"

Can you have a favourite who is great and a favourite who is an underdog?
