Unfortunately, the Texans will probably get very little for Watson if they actually trade him. But why would that be you say?
The issue is two fold:
1) What is Deshaun's motivation for asking to be traded?
He is not looking for money, his contract is set. What he wants is what Patrick Mahonnes already has. A team that can win now, and has a good chance of being a contender every year for the the foreseeable future. What he wants, is to play for a Dynasty.
So if he is traded to a team that is forced to give up all their future draft capital, or key players to the Texans as fair compensation, he will have defeated his entire purpose in asking for a trade in the first place.
2) You ask how could Deshaun stop the Texans from getting fair compensation (ie 6 1st Round Draft Picks or their equivalent).
Well our good buddy "Jack Easterby" handed his that ability when he gave him the "No Trade Clause" in his contract.
All Deshaun has to do is:
A) Refuse to show up for OTA's.
B) Refer to Cal McNair as "Tommy Boy" at every news conference or in every Tweet.
C) Have a "Back Injury" in training camp, so he cannot practice or play in games.
He does this and the Texans are forced to trade him at any price.
Deshaun with his "No Trade Clause" can then nix any trade that the Texans propose that has his new team giving up anything more than say a 3rd or 4th Round draft pick back as compensation to the Texans.
I know everyone is going to say this is a crazy "Conspiracy Theory", but this is a unique situation. This course of action, is the only path forward that meets Deshaun's goals, and Deshuan absolutely has the legal leverage to make this happen.
Deshaun is a very smart man, and is utterly ruthless in order to achieve his goals. This path is the only one that achieves what he desires, so why would he not do it.
If I were Deshaun, and crossed the Rubicon and decided to demand a trade, this is what I would do. I do not expect anything less from Deshaun.
If Deshaun leaves, he will will not play nice and show mercy to the Texans. He will stick a dagger in the Texans heart to give his new team the best chance he can to be the Dynasty he is looking for.
