I think for me once Bellinger is off the board and if he doesn't return, that when I'll be in the I dont care much anymore.
Next would be Hoskins and then the 3 with QO attached to them in Chapman, Hader, and Snell and I'd be a bit surprise if they give up a draft pick by signing one.
After those guys, there not much left that will wow me if they sign and I just dont see them giving up any of their top prospects to get back any real quality mlb player in return.
