But St-Pierre said a move up in weight would likely come near the end of his career, and it won't come anytime soon.
"If I go up in weight, it's going to be hard to go down," he said. "If I put on lean muscle like I already did recently ... it's going to be hard to come back down. So it's not like I go up and I go down. I have to be very careful with what I do."
Still, if St-Pierre takes "a couple" of welterweight fights in the next year or two, and if Silva is still the pound-for-pound king at that point, the French-Canadian then would consider moving up to fight him. And if he defeats Silva, that's a win worthy of retirement, he said.
"If one day I fight at 185 pounds for a superfight to know who is the best pound-for-pound in the world, (and) if I reach my goal, then my goal will be reached," St-Pierre said. "There will be no point for me to still compete because I'm not going to have a goal left."
Silva - next fight at 170 (pre-Maia) - when asked - a definitive yes.
GSP - this shit (basically, if Anderson Silva is still fighting at MW in two years or so like when he is 38 y.o., i'll fight him. Then i'll retire.)
This is the type of GSP shit that annoys me. GSP is beloved by most for his brilliantly boring planning, execution and takedown, 5-round decision wins.
Silva hated for bitching around every top MW contender for almost 5 years - either by spectacular finish OR mockery against easy to beat MWs (except the only real threat to him Hendo).
