Bruce Arena's first USMNT squad probably won't tell us much. The Europe-based players are unavailable because it isn't an international break, and the USA-based players aren't in shape because the MLS doesn't start for a while. Also, the games won't be anywhere near competitive international matches.
That said, it is his first squad and therefore people will wildly speculate on what his team selection means. Maybe we'll learn something about the type of player Arena is looking for. More likely we won't.
That said, here's Bruce Arena's first squad in his second stint as USMNT manager:
Goalkeepers
David Bingham (San Jose Earthquakes)
Stefan Frei (Seattle Sounders)
Bill Hamid (D.C. United)
Nick Rimando (Real Salt Lake)
Luis Robles (New York Red Bulls)
Defenders
DaMarcus Beasley (Free Agent)
Steve Birnbaum (D.C. United)
Brad Evans (Seattle Sounders)
Greg Garza (Atlanta United)
Matt Hedges (FC Dallas)
Taylor Kemp (D.C. United)
Chad Marshall (Seattle Sounders)
Keegan Rosenberry (Philadelphia Union)
Walker Zimmerman (FC Dallas)
Graham Zusi (Sporting Kansas City)
Midfielders
Kellyn Acosta (FC Dallas)
Alejandro Bedoya (Philadelphia Union)
Michael Bradley (Toronto FC)
Benny Feilhaber (Sporting Kansas City)
Jermaine Jones (Will probably play for LA Galaxy next season but who knows)
Sacha Kljestan (New York Red Bulls)
Sebastian Lletget (LA Galaxy)
Kekuta Manneh (Vancouver Whitecaps)
Dax McCarty (New York Red Bulls)
Darlington Nagbe (Portland Timbers)
Chris Pontius (Philadelphia Union)
Wil Trapp (Columbus Crew SC)
Forwards
Juan Agudelo (New England Revolution)
Jozy Altidore (Toronto FC)
Jordan Morris (Seattle Sounders)
Chris Wondolowski (San Jose Earthquakes)
Gyasi Zardes (LA Galaxy)
The good:Nagbe, Lletget and Kljestan all offer the type of attacking movement and creativity the USMNT has always lacked.
The bad: Zusi and Garza just aren't good enough to be on the team.
The ugly:
The year is 2054. Earth is largely a nuclear wasteland. Fighting over scant remaining resources is fierce. Wondo clangs one off the post.
