With JK now out, USSoccer is likely to go with a caretaker to get us through qualifying, most likely Bruce Arena. He's no lock for the permanent position unless LA & USSoccer allow him to keep both roles, which is highly doubtful - I think he's going to take his third stint at the helm simply out of loyalty to the program and getting them to the WC.
Why would he leave a well-paid job with the Galaxy if the job doesn't get him a chance to go to the World Cup? Also, when was his second stint with the team? I only recall one.
