There is some speculation that Brady jumped the gun when he rescinded his first retirement. Many analysts think that he thought he was going to join the Miami Dolphins. Everybody knows that the Dolphins didn’t have much faith in Tua Tagovailoa. They considered trading for controversial star Deshaun Watson but also pursued Brady.
In the end, this never materialized and Brady continued to play for the Buccaneers. In a way, it’s better that Brady didn’t line up for a third franchise. But he should have retired after he won his seventh ring. He has a good relationship with Mike McDaniel but there’s no guarantee it would have worked (via New York Post).
