Michael Buble -- Honors NHL Star Geno Odjick ... 'Best Hockey Fighter EVER'

Michael Buble respects a man willing to fight 5 men at the same time ... which is why the long-time NHL fan says Gino Odjick is the best hockey brawler EVER!!!

Odjick was a BEAST out on the ice during his 12-year run in the NHL ... but Buble says his favorite memory ever is when the guy tried to fight an ENTIRE hockey team at once.

We think Buble was talking about an incident in May '95 ... when Odjick went after several players on the St. Louis Blues.

Odjick is currently battling terminal heart disease ... and just like when he played, Gino says he refuses to go down without a fight.
