I think the only "obvious" one is Coleman Crow, and perhaps I'm the only one that thinks he should be protected.
I guess I kind of disagree, but mostly just because he needs innings to bring his numbers back down. He needs 5 innings at a time in order to bring down his BB and HR rates. He needs innings so that he can pitch around guys, and get through an order a couple of times. Lots of soft contact, trying to minimize damage. He's ONLY valuable to a team if he's going 5.2 innings. Bringing him out of the pen in the 6th inning in a one-run game isn't ideal for him or the team. His stuff simply doesn't allow me to envision him being successful in any relief role, other than the mop-up role.
I think he and his agent know that if he goes into free agency as a "swingman," it will cost him millions of dollars, or at least $1M. Not insignificant. He's simply not that valuable out of the pen, particularly with his elevated walk and HR rates in the last couple of seasons.
Throw in the fact that his body doesn't scream "well-conditioned athlete," and I would be concerned about his ability to bounce back on short rest --- again, for the first time since he was 20 years old.
I think Civale and his agent are correct to "panic". His upcoming free agency could be very boom/bust for him. If he were to re-set his value with a strong summer in the Brewers rotation, teams may be willing to get to 4 or 5 million AAV. If he remains as more of a depth starter, he's looking at 1-2 million AAV.
