What fights are there that if there was a rematch made, the loser of the first match would be the favourite in the second match? For example, Khan beat Maidana but if they fought again I think Maidana would be favourite. I think if Lomachenko fought Salido again, Loma would be slight favourite. What other examples of this are there?
Not sure whether Hopkins was favourite vs Taylor - don't think he was. He might have been favourite vs pascal although he wasn't loser first fight. However, pascal did retain his titles because of the draw
Khan - Garcia and Matthysse - Garcia would be close in the betting I think, considering how Garcia looked vs Herrera. A recent example was Froch being favourite against Kessler after Kessler won the first fight.
Officially yes, but thats because almost everyone knew Pac won the first fight. Pac was favourite vs JMM4 even though most people knew JMM should have won the 3rd fight but got a bad decision. Pac would probably actually start favourite for a 5th JMM bout also.
