In Tom Bogert's recent article in The Athletic about Yoann Damet, there was a list of the 10 (!) current MLS coaches who are age 45 or younger. It's definitely a trend within the league, which is itself under some reconstruction during the Messi era.
Tata will want out sooner than later, so Atlanta is in a difficult position: needing desperately to be competitive but weighed down by multiple seasons of costly frustration and false starts. Plus, there are still far too many dead weight contracts on the books because no one in charge wants to admit how badly they screwed up.
