Idk, I think Bourn still has something left in the tank. He's been working on getting fully healthy for this year, and if he is he'll contribute. Plus I think Kipnis is due for a rebound year and Moss was a good acquisition. There's a lot of young-ish talent on this team (Kip, Gomes, Santana, Brantley, Ramirez, Lindor, and I still naively believe Chisenhall could turn out decent).
Jason Kipnis; aside from that absolute MONSTER month in June of 2013, he's been a career .250 hitter with 10-12 HR's. Hopefully a return to his natural position in the outfield will change that. Like you, for whatever logic eludes me, I remain optimistic about him.
Bourn; I'm much less optimistic about this cat. I hated the deal the day they announced it due to his age (at the time a year or two over 30) and the fact he lived and died with his legs. And over 30 year olds who depend on their legs are always a big question. He still strikes out more than he puts the ball in play, still hasn't figured out how to bunt despite being a "lead off" hitter, injury prone, has a grand total of 33 SB's in TWO SEASONS, but does play above average center field. I'm crossing my fingers, man.
Swisher. Get rid of him. Pay half his salary to play elsewhere if that's what it takes. Just send him far, far away. He was a 20 HR guy in NY where the right field was once described as "the biggest joke in baseball" by Peter Gammons. You and I would hit 20 there! He kills pitchers who are like a #5 guy in the rotation. But he's never hit a #1, #2 or #3 pitcher in his life, and in the post season, that's all you face.
I agree that we've a lot of good youth. Nothing but love for Santana, Gomes, Brantley, (hopefully Lindor) and yes, Chisenhall. I like a veteran David Murphy at the bottom of a lineup, too. Still a good bullpen, as well. Pitching > hitting, so things could get interesting.
