All Valid areguements Speed kills and always has!!! Floyd can take a punch and his defense is incredible period!!!!!! He is deadly accurate and very selective about his punches and is always poised thats how you preserve energy physical and nervous he can go 20 rounds if he had 2 and stilll be fresh..Hearns is great and had a superhuman right hand, Floyd counteracts that with different angles faints counterpunching Hearns had alot of heart but not smart enough to adjust...do you remember Corralles vs Maymeather Diego and Hearns similar body type combo of speed and 1 punch knock out power...Diego could never get off against Floyd couldnt figure him out 2 many angles..But against castillo Diego can trade go figure!!! Boxing is all about matchups Not a good one for hearns
