Real Salt Lake brought back Brooks Lennon on a permanent transfer earlier this week, locking up the 20-year-old winger after he spent 2017 on loan to RSL from Liverpool.

The signing keeps together RSL’s exciting young core, which includes Jefferson Savarino, Justen Glad, Danilo Acosta and Sebastian Saucedo, all of whom, like Lennon, were 20 or younger during the 2017 season.

Together, that group of U-21 players played 6,819 minutes in 2017, the most of any such group of players on any team in MLS in 2017.

Here’s the full table for MLS minutes played by U-21 players in 2017, by team. As you can see, RSL led by a wide margin, while a couple of teams at the bottom of the table, notably the Houston Dynamo, just missed out on ranking high on the chart, with several 22-year-olds playing significant minutes.
