The article had some really great quotes from Andy Powell (and Centro Sr. of course).
Andy Powell said:
#1 On this year's Training/the OTrials:
"Really, he wasn't in great shape. He was not where you want to be. But now I really feel that he'll be that way as he hits the Olympics, that his training is leading well up to that."
#2 On last year's training before worlds:
"We switched up his training, did our own thing and tried to get him strong going into that. A lot of people hit speed work. We got him strong. I really wanted him to make the finals. That was the goal. I thought that'd be a nice place to start."
#3 On centro being ignored/clutch:
"I think he gets lost a bit because he does not always put up the flashiest training times. But he's clutch. He runs well when he needs to."
