I said that he may not be in the rotation by the end of the season, but he is a no doubt major leaguer. He'll be pitching here or another major league club at the end of the season.
I also said Olsen is a proven major league pitcher; wish I had made some avatar bets. When was the last time a Nats starter had 8K's? Zimmermann last season, I think.
I think you're playing with fire if you get rid of Lannan.
