There's a popular hashtag on MLS social media that people like to use -- #PlayYourKids. Basically, when you play your young players -- your kids, so to speak -- good things can usually come out of it in the long run. Sort of like September call-ups in baseball for your best prospect, or getting that rookie quarterback minutes for your 2-8 football team.
If there's an opportunity to get a young player minutes at the first team level, then take that opportunity and go with it.
Orlando City has done a great job with that since entering MLS -- maybe not by choice, however, as the club had the youngest team in the league last season -- and has continued to run with the idea this season.
