I'd stay away from Hamilton. He'll be declining soon. We need to save our $ to give extensions to JZ, Desi, and eventually Stras and Harper(though those won't be for a while).
The big question is, how do we handle Laroche/Morse? We can't keep both. Morse has I believe 1 year left, so if we resign Laroche I'd look to trade Morse. We need to see what we have in Moore though and he's a natural 1B. Harper will likely take Laroche's spot as the 4 hole power hitting lefty.
I think we'll stick with Espi for one more year. We were all raging about Desi this time last year and look how he panned out. Espi is a year younger so hopefully next year will be his breakthrough year as well.
I'd also say no to Grienke. The guy is as mentally weak as they come and he's a lock to choke in the playoffs. Plus he said no to us before when we were bad, now that we're good I'd rather tell him to **** off. Stras/Gio/JZ/Det/Lannan is a fine rotation.
Bullpen...well it's really hard to evaluate a pen. Relivers are so volatile and change so much year to year that it's hard to say. If we could get a reliable vet or two who are still fairly young and have postseason experience though, I'd go for it.
