The start of MLS soccer is just around the corner, with the Union's home opener fewer than three weeks away. With that in mind, and the team heading down for the final leg of the preseason, now's the perfect time to sign up for MLS Fantasy and start thinking about roster construction. And look no further than in Philadelphia's own back yard.
Keegan Rosenberry is the most popular defender in MLS Fantasy, and the second most popular play among all positions. Rosenberry, aiming to build off an all-star rookie season, is being selected in 37 percent of teams, trailing only Toronto FC's Sebastian Giovinco, who is being selected in 42 percent of teams.
