Yes, the Brewers have to rely on the development of younger players. I should have mentioned Contreras being the younger players category. While we are all excited about him, he is still far from proven. While Turang/Mitchell/Frelick are decent prospects, they are not those can't miss Top 10 guys where the hit rate is pretty high.
Getting a veteran on a one year deal to help mitigate risk is what smart teams do. If the rookies provide production, you play them. If they fall on their face and need to get sent down, you aren't sunk. I would prefer to not have to watch the Pablo Reyes types if at all possible.
Tell me what World Series winner started 3 rookies in the field, much less 2.
