Bill James has said the Boston Red Sox have made some trades with other teams with the understanding the team won’t subsequently trade that player to the New York Yankees. To the best of his knowledge other teams have never gone back on their word.
If Colorado did this with Rantanen, do they limit it to just Dallas? What about Edmonton, Los Angeles and other western teams? Plus Carolina is under pressure to sign him (which didn’t happen) and they apparently decided not to trade him to Toronto because, like Colorado, get him out of their conference.
To me, a GM/owner should worry about his own team. KISS. Keep I Simple, Stupid
