I'm a boxer and I got Seagal winning in a street fight. Seagal in his prime DIDN'T have a big belly like that other guy said. He was strong and in shape. In his prime, Seagal puts Lennox in the hospital in a street fight. In the ring, Lennox wins allllll day!
Seagal is 6'5 himself, so height wouldn't be an advantage for Lennox. Seagal is the real deal, if you don't think so, you are blinded by his movies and hollywood persona. When he was young, he was bad azz. If Lennox couldn't hit him, he'd get taken down and it's over.
I'd say in a street fight, Lennox wouldn't stand a chance, that's just my opinion. Seagal was the first foreigner ever to operate an Aikido dojo in Japan, ever.
I grew up street fighting and I am a pro boxer and I guarantee Lennox wouldn't even fight Segal in the street. Wait, I take that back, prime Lennox would fight a past his prime Seagal just like he did in his real career to other Americans.
