I think I understand the question, I just don’t understand the reasoning of the question.
If I’m understanding this unlikely conversation correctly, Dolphins call up the Chargers, and one of the teams says “hey we really like Tua, you’re not taking him, right?” and the other team says “oh no man, you’re good, we want Herbert.”
And then they form a BFF pact, saying that neither team will trade up? Well if the Chargers want the QB that we don’t, we don’t really care if they trade up or not, right?
Ok, carrying on with this scenario, this new Justice League agrees to team up, nobody trades up.... except the Patriots for Tua because neither of the other teams would get suckered into a trade
