Wilson should be pitching the highest leverage situations against LHH in the postseason. Throwing him in the closer's role then asking Strop, Cishek, or Chavez to get the biggest outs against LHH seems less than ideal.
But it would fit with Joe's historic lack of confidence in Strop. He's been consistently good since the day he joined the Cubs, but Joe has always seemed to look for reasons not to trust him.
