From Eric Branch's article, recently posted on the forum main page--
Rivera was Singletary's backup at middle linebacker on the 1985 Chicago Bears and later played alongside Singletary for five seasons. Rivera notes that Singletary, the Hall-of-Fame player, had a unique ability to absorb Xs and Os and the subtleties of the game. It's not a trait generally assigned to Singletary as a coach.
Is this not the most shocking thing that anyone has written all week? This is the same man who inanely claps on the sideline after every single play. I'm not as a big a Singletary hater as most, frankly I think he isn't a bad coach. (I think he is great at getting the most effort out of his players) But, an x's and o's genius? Give me a break.
