Pac has to be careful for a couple of reasons. Firstly he cant let all this media speculation distract him from his first task, defeating Hatton. Take Ricky lightly and he could get hurt, and all these big fights will be out the window.
Pac also has to realise his limitations. He wins a lot of fights against fighters who are arguably more skilled than him thru having speed, strength and chin. Against Mosely he would be giving up atleast 2 of these (strength and chin) and maybe even 3 cos Shane aint slow.
I guess we'll know a lot more after the Hatton fight but i think if Shane is at the same level he was against Margarito in a Pac fight he takes out Pac in 6.
