This is a troll question. Michael Brown was around 6 inches taller and around 150 pounds heavier. Despite the nonsense that George Zimmerman, his supporters, and his defense team claimed that Trayvon Martin had all of these black belts in all these martial arts systems, Trayvon couldn't even take Zimmerman in a fight even if ZImmerman was unarmed. No way Trayvon would stand up to Michael Brown.
Trayvon was an athletic but lanky 17 year old who was still in the throes of puberty. Michael Brown could have played offensive tackle at a division 1 school.
Martin
Michael was bigger, and Trayvon is smaller, I think Micheal would. (I know this is a troll)
The end result would be dead even!
