MLS has published full and detailed lists of its teams' rosters, providing a near-unprecedented insight into the precise construction of each squad in the league. It is a welcome step toward greater transparency from a league that - even to those who work within it - can be a little hard to follow at times.
The roster lists provide a snapshot of where teams are right now: squads can and will change over the course of the season. Still, they provide a helpful understanding of how a team has been assembled for the start of the 2017 MLS season, and one or two surprises.
