According to Grant Wahl, that was the only reason he wasn't called

I'm assuming there's more than one legitimate reason for Pulisic's omission. I'd prefer that Ream and Bedoya not be on the squad, but the omission of every big name US "star" is smart moving forward.

I wonder if Bosz requested he be left out to keep him fresh and focused for upcoming club matches.

Looks like the guys who are training in Europe are being left there for the most part (Weah, Pulisic, Klinsmann, etc.). Bobby Wood is nursing an injury, and Jonathan Gonzalez has a big Liga MX match coming up this week.

I would imagine the smattering of some vets is just to have some experience on the squad, which probably helps integrate the younger guys. But it has to be the right ones with the right attitude, so I'd rather have Bedoya and Ream than Bradley, Altidore and Dempsey. Thankfully all three are still playoff engaged.

He's always kind of straddled the line between great feistiness and acting petulant. Which can either work out well in something like CONCACAF matches, or go horribly wrong. See his US Open Cup fiasco.

US Soccer needs some fresh faces. Altidore, Bradley and Clint were all scowlers.
