Unless he respects that he signed a contract to the end of 2020, and is going to honour that, whether they take him to the Tour or not.
But what is in the contract. It most likely contains clauses about guaranteed Tour selection and protected status. In 2012 when the stuff was going on with him and Wiggins he had a copy of his contract sent to him at the race as it had similar agreements in it. I expect it still does.
If Brailsford wasn't prepared to meet the terms of the contract Froome could have got himself released and moved in August. I expect they will have come to an arrangement.
