It’s been widely known for weeks that Trevor Thompson has put his name in the NBA draft as an underclassman. Today, when the league released the full list of 137 underclassmen to put their names in for the draft, it also included Ohio State guard Kam Williams.

Neither player has yet hired an agent, leaving open the option to return for the 2017-18 season. Both players are fourth-year players, with Thompson redshirting after transferring from Virginia Tech and Williams redshirting as a freshman due to illness.

The 6-foot-2, 185-pound guard increased his scoring average from 8.3 points as a sophomore to 9.4 as a junior, but his production diminished down the stretch after being thrust into a starting role due to the season-ending injury to Keita Bates-Diop. After shooting 43.7 percent from three two years ago, Williams shot 37.6 percent last season.

In 102 career games including 31 starts, Williams has averaged 7.6 points while shooting 42.4 percent from three (286 for 675).

This is the second year in which players are allowed to declare for the draft but retain their eligibility providing they do not sign with an agent. Underclassmen had to submit a letter signifying their intent to test their draft stock by April 23 and they have until May 24 to withdraw their names and be able to play next season.

Players who are not invited to the NBA combine can work out for one team and be evaluated before May 25. Last year, more than 70 players were invited to the combine. Thompson was not one of them, and he returned to Ohio State for his junior season.
