The fatigue factor for the Galaxy is a continuing issue, especially with the club dealing with so many injuries. The thing is, for those who point out that many clubs around the world (including their SuperLiga foe, Pachuca) play just as many games, if not more, the truth is that those teams do so with more bodies in their rosters. That allows them to rest and rotate players.
That's part of the reason that I was surprised that the league didn't expand the roster size this year, even while adding a new tournament, like the SuperLiga.
Where MLS is lacking more than any other aspect in comparison to bigger and better leagues around the world is in roster depth.
