I too have noticed that for the most part, the power just isn't all there at 154. Strange that 7 lbs would make that much of a differnce but it seems too. But you must also remember who else is out there at 154 now, a bunch of ex-147lbers just like Mayorga. Ya got Quartey, Forrest, and now Spinks :P Plus I for one think IF Mayorga does fight again, a match up with recently dethroned Alex "terra" Garcia would be very exciting.
