Sounds like Bourbeau was reluctant to fight Flipper (judging from what the announcers were saying) and if that was the case he was pooched from the start. You go into a fight not thinking you have a chance, you're gonna get embarrassed, let alone a top heavy who does nothing but box in the off season and loves to fight.
I fought Bourbeau in Junior, he's a tough kid, but I remember watching Flipper play Junior A in my hometown for a few years and never once remember seeing him lose and he fought anyone and everyone. ALOT. He's in a league if his own.
