Centro was boxed until 75m left. He overcame the bad tactic. "Boxed in" is already defined, so don't foster a new definition for this thread only.
In a season when a HS junior finished 10th, no one can say Centro wasn't capable of 1st. I would've liked to see a "free" Centro uninhibited from 400m out. He finished 2011 WC in :51 in a 3:36 race, gaining ground on everyone that last lap, but was back at 1100m.
Hey, aren't you the guy who said Ritz had a good shot at a medal?
Sorry, but you lost all credibility with that one. From there on out your posts are good for a laugh - nothing more.
