CAn he do it quicker than Cotto? I think he will blow Jennings in 4. http://www.skysports.com/story/0,19528,12183_5456360,00.html
Brook in 5 rounds. Jennings wont be able to handle the speed and power straight from the opening bell.
i don't know much about brook. i've seen some highlights and he looks pretty good. i know jennings isn't all that great, so of the options, i guess i have to go with brook ko.
