22. Sporting Kansas City CB Erik Palmer-Brown: Age 20
21. Tottenham CB Cameron Carter-Vickers: Age 19
Carter-Vickers has an interesting story. The son of former American basketball player Howard Carter, Carter-Vickers was born and raised in England. It's very feasible to assume that he's good enough to play for the England youth National Team set-up. However, Carter-Vickers opted to suit up for the United States.
Carter-Vickers is a bowling ball in the heart of the defense. Though he's equipped with the frame of a burgeoning body builder, Carter-Vickers has good short-area quickness and technical ability. He's also an absolute beast in the air. At only 19, he's on the cusp of breaking through into the first team for Tottenham. Assuming the respective developments of Palmer-Brown and Carter-Vickers continues, we could be looking at the future United States centerback pairing for the next decade.
20. Los Angeles Galaxy MF Sebastian Lletget: Age 24
After a lengthy stint with English club West Ham, Lletget returned stateside for more of an opportunity at first-team football with the Los Angeles Galaxy. A robust player, Lletget bombs up and down the flanks routinely. He's a crafty player with the ball, and is adept at picking out teammates with carefully constructed passes.
Lletget suffered a rather serious foot injury this past March, and will be out of commission for the next few months. At only 24, he certainly has a bright future in MLS -- assuming he gets back fully healthy.
