I've voted for Pac by UD.

Here are my reasons:

Pac if he trains with full concentration and no distractions, he will come fully prepared.

Allthough JMM beat Barerra, I thought it was a close fight and allthough at this stage in their respective carears JMM poseses more danger to Pac than Barerra would, IMO Pac will have the measure of JMM but only just.

JMM has amazing skills but a slighlty younger and fresher Pac will be abit to much to handle, I mean it's a very tough call but this time round I believe we'll see Pac start very strong and finish strong, with the middle rounds going to JMM.

JMM will be fully up for this fight of that there is no doubt and he will make the fight difficult for Pac, but if Pac takes this fight very seriouslly (and I'm sure he will, he has to) then the greater speed and punching combinations and the accuracy of the combo's from Pac will see him to a UD.

I see JMM working from the outside and using his own speed and combo's but I see Pac hitting harder and working on the inside and then getting back out and going upstairs.

I know I've gone on abit so to sum it up.

Pac will have the greater workrate and better punch combo's due to his speed.
