gatti is one tough SOB who doesnt back down to no one, Id go far as saying he couldve even fought with a middleweight and wouldnt give a f**ck if he would take a beating or not, blood and guts right there. however as far as him being scared of the overboard pyrotechnics during the floyd fight my answer is definitely yes. he literally almost jumped off of his feet while closing his eyes when the explosion occured....:fire
I would say he was startled not scared. There's a bit of a difference. He probably wasn't thinking of it by the time he was climbing in the ring.
