Are you saying these fighter did not have a jab ? if you are then Im leaving this site for another 6 months ..
in his early years although pac used a jab it was usually just a short feint or a range finder for his straight left. Lately he's thrown it with more conviction but i still wouldnt call it a good weapon of his
He was outjabbing Cotto though ... so id say Pac can definitely jab by now. I would agree with the Pac of several years ago, he was a boarderline great fighter at that point that got by without a great jab.
