Pac has very good defense statistically so it'll be pretty low. And he'll throw less than ever before, afraid to open up.
Jab connects will be a very low %. He uses it as a pawing range finders against southpaws and doesn't throw it with much intention to land. He landed something like 6% of his jabs in the first round of the Ortiz fight and only 14% overall.
The lowest you're offering is 30-35? I'll guess high 20s overall with the percentage climbing as the fight goes on.
