Clayton Custer

After going undrafted in the 2019 NBA draft, Custer signed his first professional contract with Śląsk Wroclaw of the Polish Basketball League.

As a redshirt junior, Custer led the Ramblers to the Missouri Valley Conference regular-season title, despite missing five games to an ankle injury. Custer was named the MVC Player of the Year. Following a run through the 2018 MVC Tournament, Custer and the Ramblers entered the 2018 NCAA Tournament as an 11 seed. After a first-round win over the Miami Hurricanes, Custer led the team to a 63–62 second-round win over Tennessee. Custer hit the game-winner with 3.7 seconds left to advance the Ramblers to the Sweet 16. He ended up leading the Ramblers to the Final Four while averaging 13.2 points and 4.2 assists per game. At the close of the 2017-18 season, Custer was awarded the Lou Henson Award for top mid-major player in the country.

As a freshman in the 2014–15 season, Custer played sparingly behind the Cyclones' Monté Morris, one of the top point guards in the Big 12 Conference. He chose to transfer following the season, after scoring 13 points in 12 games. Custer ultimately chose to re-join Richardson under coach Porter Moser at Loyola after Moser took him to lunch and met with his parents. After sitting out the 2015–16 season per National Collegiate Athletic Association (NCAA) transfer rules, Custer immediately joined the Ramblers' starting lineup, allowing star Milton Doyle to play off the ball. He averaged 11.6 points and 3.1 assists per game as a sophomore.
