Personally, I don’t think he can really help or hurt his value over the next few days. A couple good or bad games isn’t going to do anything at this point. Get him on the field.
I don’t see the benefit of putting it out there that he’s out with groin tightness, if it isn’t actually that. Teams already have to be skeptical of his injury history.
You don’t hire Boras and then take a deal that’s potentially team friendly. Period. If a team buys him out, he’s taking likely a 1-year, highest possible AAV deal to rebuild value.
