Personally I am starting to think its as good as any jab out there... He has been landing it on everyone, and sometimes he hits so hard that it lands the hardest punch of a round full of hooks and crosses... I seriously think he has the hardest jab p4p, and he gets it out there so fast with perfect timing... I am just trying to think where it would be p4p
My list
1. Winky Wright
2. Rafael Marquez
3. Oscar Dela Hoya
4. Wladimir Klitschko
5. Miguel Cotto
6. Mikkel Kessler(I don't think his jab lands enough)
7. Ike Quartey(if he is still fighting, but in his prime that jab was dope)
8. JMM, he has always had a great jab
9. Floyd Mayweather Jr., technically one of the greatest jabs I've seen, but he doesn't change it up enough which makes it easier to block.
10. Manny Pacquaio, I have always loved his jab its hard, and is thrown from a million angles.
