Tarver KO'd Jones and he's a southpaw. Pac is a southpaw but better. Therefore Manny KO1 is the only logical answer.
:::bears: Seriously, I refuse to answer on the grounds that p4p matches are retarded. At 154lb I'd go with Jones by knock out.
Theres very few fighters who I'd even give a chance of beating a prime Jones in a P4P sense..... Manny however I'd give a legit chance. However, I just cant favor him over the 168 Jones in a P4P sense. Manny is fast as all fuck, but against a prime Jones... for the first time in his career... Manny would find himself getting beat to the punch consistently.
