Hmm 23 man roster. Assuming everyone is healthy. Here goes bolded names are locks
Goalkeepers (3): Howard, Guzan, Robles (don't really care about the 3rd keeper, but there should be 3 on the squad just in case)
Defense (7): Gooch, Cherundolo, DeMerit, Spector, Bocanegra, Hejduk, Pearce?
Midfield (9): LD, Dempsey, Bradley, Clark, Jones or Pablo, Edu, Torres, Feilhaber, Adu
Striker (4): Altidore, Davies, Ching, Kenny Cooper
That's my best guess right now. The 4th striker seems like the biggest ? as well as who gets the final MF call-up: Adu, Torres, Edu, Feilhaber, or someone else. DMB is out, Sacha is out, Wynne is out, as is Connor Casey who didn't do a GD thing in the Confed Cup. I'm a bit concerned about the 7th defender on the squad. I have little confidence in any of the guys except for those I listed 9and little confidence in Pearce, although I think he's the least worst of the bunch).
