Donaire has ridiculous left hook. So much power and very good timing. Who hasn't he knocked down with that left hook?
You know it! That left hook he pulled off vs Hatton in round 10 was just brilliant, never seen anything of that calibre ever.
Mannys left hook out of his southpaw stance knocked Hatton cold instantly. Boy, u walked into that one harder than Hatton did atsch
Yep! Felix also a master of distance could land that hook with regularity. Like most great left hookers he throws it from the inside, and had great snap on his punches.
He kind of threw it in a hook motion. It was travelling more clockwise than straight. You get a better view on the replays, particularly the overhead shot. http://www.youtube.com/watch?v=xInP9Gi0xAA
Trinidad had a great left hook but I don't know about top 5. There's been many great left hooks throughout history. It'd be pretty hard to come up with a list. But taking into account numerous factors, like versatility, overall effectiveness, power, I'd have to go with SRR.
