I'd like to see some creativity deal making for a closer without going so far as to crapshoot. I like Kimbrel better than Iglesias, but both feel like they have the potential to bust (though every closer does) with a high price tag. Kimbrel falls into inexplicable seasonal slumps between seasons where he's untouchable, and Iglesias lets nearly one out of every 5 flyballs leave the ballpark. That sounds like exactly the kind of guy I don't want to see, or give up a draft pick for.
Kendal Graveman is an interesting option. Stuff-wise he's kind of like Ian Kennedy- throws hard without a lot of k's, but instead of living up in the zone and being homer-prone, his 2-seamer is pretty wicked. His stuff also seems to be evolving and getting better. Pair him with an acquisition of another late inning reliever that can strike people out and I'd be happy.
