He does need to do the tests because how can he go from struggling against Marquez and having to go 9 rounds before he did away with David Diaz and now he is big enough and strong enough to beat these bigger guys more comfortable? he needs to stop all the catchweight bollocks as well getting Oscar to weigh 147lbs asking Mosley to weigh 143lbs Cotto 145lbs and Margarito 150lbs. He is a good fighter but it seems theirs always some sort of edge in his favour in his recent fights Oscar weight drained beyond belief Hatton was shot Cotto weight drained Cotto hadn't weighed less than 146lbs since 10th june 2006 and had been battered by margarito and nearly lost to Clottey. Clottey just came to last 12 rounds and Margarito had to weigh 150lbs and had been demolished by Mosley so he needs to fight a real live challenge rather than trying to pull the wool over our eyes because he's not doing anything we've not already seen as such.
