He didn't move at the speed of light, he couldn't put his first world class opponent off his gameplan. You couldn't look at him and prepare thats exactly what Barrera did, and totally changed how he normally fights in the process.

He also had one of the worst defences going, his balance was poor at times, he got knocked down by journeymen and past their best fighters who weren't really good to begin with. If he couldn't knock you out he looked poor check out the Mcoullough and Soto fights, he lost his first major big time fight in a 1 sided boxing lesson were he got humilated then went back to fighting bums, had 1 last fight were he looked really poor and got booed by his own fans then disappeared.

Look at Morales career then look at Naz's, huge difference !!
