When last the Philadelphia Union lined up, in their MLS Playoff match at BMO Field in Toronto, their back line consisted of Fabinho, Richie Marquez, Ken Tribbett, and Keegan Rosenberry. 2017 has brought changes to the roster and changes in health status, therefore changes on the depth chart. Two of these men are sure to be starters come March 5th (health issues notwithstanding, *knocks on wood*), but two of the spots will likely have a different starter than the last time the Union were in Canada.
I’ll start with the obvious answers: Keegan Rosenberry is the Union’s number one at right back.
