Andy Najar is back home with D.C. United but still on the road back to full strength

“There have been concerns about durability,” said Dave Kasper, United’s president for football operations, who signed Najar in 2010. “We saw in LA last year that he was struggling. He couldn’t stay in the field. We tested it and found a real hamstring deficit. That was a priority: let’s make it stronger and think about it for the long term. “
