The conglomerate of Keuchel, Velasquez, Cueto and Davis have combined for a 4.27 ERA this season. Very respectable for #4/5 starters in your rotation. And when Lynn returns, you gotta keep Cueto in the rotation. Davis becomes terrific AAA depth and I guess Keuchel and Velazquez become long relievers. Barring injuries, the starting rotation is the least of my concerns with this team.
