Jonah was a Champion Sprinter all the way through his High School Years (Read his Biography, one of the photos has his School Athletic Day results, and Jonah won everything, from the 100m to High Jump to Shot Put) - Combine that with a 1.98m and 118kg Frame, and you have the ultimate weapon. Tuilagi from what i've seen is slow and cumbersome and is just fat.
i saw tuilagi for the first time this week. in the english final. he reminded me alot of Lesley. except not as big. les is built like a tank. Tuilagi looks quicker and more athletic.
Jonah was just awesome. his power and speed were out of this world.
his defence though... highly underated. he was slow to turn but he could knock you into next week if you ran at him. the best part of his defence was when he was defending the line. he stopped soo many try's like that. i remember when he stopped Dean Hall with the ball a fingernail away from the line.
