I think Morales fought smart on the first one. Pac would go after Morales like a bull against a Matador and Morales would just move to one side and jab jab. Morales took advantage of his reach and would just fight outside dominating the whole fight and not being in a risk at all. At the end, Morales came out clean while Pac's face showed the opposite. In the second fight Morales tried to exchange punches with Pac and that's how he started to get connected here and there and slowly get worn out.

Morales should fight outside and take advantage of his reach. When Pac charges move away and jab just like he did in his first fight.
