i think its been done a few times but i am glad you did it again because there are new posters here and some of us (like me) have only recently come back. IMO Sanchez would be a slight favourite. I think Alexis was at his best at 130. Alexis is still a GREAT featherweight but i think Sanchez's speed will allow him to stay close, land quick combos and smother Alexis's punches. However, Sanchez will get rocked a few times. I don't see this as one sided at all. I expect Sanchez would win a 8-7 or 9-6 decision (assuming its a 15 round fight)
