Mike Flanagan was the best student of people, the toughest pitch-hurt competitor, the most unselfish teammate and the best world-leery wit of any Oriole of his time. Nobody was like him — at all. A few years ago, the O’s honored Earl Weaver with a plaque that’s on the wall, waist-high, in their dugout. “Oh, life size,” Flanagan quipped. When he was a kid pitcher who allowed too many steals, Flanny threw a sideline session as Weaver watched. Suddenly Earl began running, yelling, “I just stole second on you.”
