I didn't say he wasn't. I just think that he'll have plenty of chances to succeed, even if success doesn't come all that quickly.
I will say that, looking at his numbers last year, he definitely looks promising. I like that Rizzo has created a kind of pipeline of relievers where, as one goes down or is traded, there are players in the minors who can step up and take that spot. There are a few guys in their mid 20's in the minors like this.
