MLS has a long history of trying to tweak the rules to promote a desired outcome and they are prepared to make a change to promote academy talent. First reported in December and re-confirmed today, MLS is adding two additional roster slots specifically for homegrown players. The slots would bring the total roster size to 30.
The specifics of the HGP roster slots will be disclosed when MLS releases the revised Roster Rules and Regulations before the season, but the effect will be to provide extra value to teams that have a strong development pipeline.
