It is decidedly not true that 'nice guys finish last'.
You don't save a pitcher for tomorrow. Tomorrow it may rain.
And luck? I've always said about Dizzy Dean that if the roof fell in and Diz was sitting in the middle of the room, everybody else would be buried in the debris and a gumdrop would drop into his mouth.
When you're in professional sports, winning is the only thing that matters.
Win any way as long as you can get away with it. Nice guys finish last.
Show me a good sportsman and I'll show you a player I'm looking to trade.
