Pettis' only clear cut challenger right now is TJ Grant honestly, the #1 contender.. No other fights really make since at 155 for him, and the Aldo fight IS the fight people WANT to see. So for Pettis pushing this fight is brilliant and Aldo did agree to fight him before, BUT Pettis was the only who pulled out I understand, not Aldo. Pettis doesn't have much to do at 155 atm.
At 145.. Edgar, Lamas, Swanson, Poirier all guys who are on the edge of a title shot...BUT Pettis/Aldo is a fight people want to see.. Make some legit #1 contenders after they make Pettis/Grant & Aldo/Lamas.. If they both win then set them up in a super-fight.. That is what makes perfect sense to me.. Then after that 145 and 155 should have some legit #1 contenders for the Titleshots.
