If you must drop one, drop Lindstrom. It's a non-keeper league, so you're talking about 7 weeks basically, and if you drop Nunez, you know you're dropping someone with valid closer duty for AT LEAST a few weeks, possibly the remainder of the season. There is a chance, if Nunez blows a couple, that he'll lose the job, but he might not, and you'd be giving up a viable closer to someone else in the league (of course, depends how rare closers are in your league, how saves are valued, etc). I would drop Hochevar over either, however, especially if you want to make sure you don't lose a closer. He has a decent ceiling, but I wouldn't expect too much this season.
