I've seen those quotes, and I really do not understand for the life of me why an owner being excited about a possible player would mean they undermined the well-understood fact that deals are contingent on a physical.
I actually disagree with this -- it sounds like the type of advice overly cautious lawyers give to CYA, I would be really curious to see any examples of arbitration being impacted by owner comments, because I cannot imagine an arbiter is that transparently silly.
Like I can see it mattering for the purposes of say a raise for Happ, if the Ricketts were out there making comments about how important he was to the team, but I don't see why it would hurt a team's ability to make a deal contingent on a physical.
Probably hard to research but that's my hunch.
