You can't make up your own rules because it suits you. You considering a player on the team doesn't make it so. A contract is required.
And, lest you forget, my post said he "technically" wasn't on the team, so I recognized he was likely to be a Cowboy, but you wouldn't accept that, despite the facts.
Ask yourself what are the elements of employment. In the NFL it involves a contract, but on top of that, universally it means a person is on the payroll, is getting paid, and is obligated to perform the duties of the job. None of those things applied to the relationship between the Cowboys and Dak at the time of the 2020 draft.
As it has been said, you are entitled to your own opinion, but you are not entitled to your own facts.
The obvious reason I'm telling you about contract negotiations is because you oddly equate the notion of Dak sticking with his negotiating position as acting like a petulant child. You seem to have no understanding that it is a business maneuver, or that a negotiation tactic doesn't work if the party doesn't appear to be serious about the position they take.
That's what I said was going on - that Dak wasn't under contract, and as part of the negotiation he had to maintain his leverage by showing he was serious about his position.
Those are the facts. You have no facts, and are going on emotion and what you want to believe.
