The combine provides opportunities for Caribbean players to be observed by MLS scouts with the hopes of being invited to the MLS Combine, an invite-only showcase event held in Fort Lauderdale, Florida prior to the annual MLS SuperDraft.  The combine is part of an agreement between the two entities as they try to promote football development throughout the Caribbean region.  About the impact of Caribbean players on the league, MLS Technical Director Alfonso Mondelo said, "Quite a few players have played, continue to play in the MLS and have done so successfully...Now we are looking forward to the next generation of players who will be coming in", while MLS Executive Vice President Todd Durbin said, “We recognize that the CONCACAF area, and particularly the Caribbean, is rich with soccer talent, and this will be an opportunity for our scouts to evaluate and identify the region’s top players...Caribbean players from islands like Jamaica, Haiti, Grenada and others have been key performers in MLS.  This event will help recognize the next generation of MLS stars as we look to achieve our goal of being among the best leagues in the world by 2022.”  From a Caribbean perspective, CFU President Gordon Derrick stated, “As CFU Member Associations turn their attention to Russia 2018, this is an exciting developmental opportunity for the opulent young talent in the Caribbean to assess their developmental level and the growth required to play at the highest level...This partnership with MLS is another way in which we at the CFU are seeking to bridge the gap that exists between talent availability and scouting opportunities that the Caribbean region has received from professional leagues.”
