as far as ive seen with him, his success depends on him getting ahead in the count, his location, and pitching efficiently. When hes not down in the damn count the whole night, and when he can keep his pitch counts down hes pretty damn good, but he just hasnt been doing that lately. Its not matter of his stuff going good, but his head going good. You could say that for alot of pitchers, and it applies to him. Id say give him the rest of this year, and part of next year to work on it, If he doesnt get traded in the biggest white flag trade/management clearing house to ever happen in baseball, that is going to happen sometime shortly after the all-start break
