Numerically, sure. Effectively, not really.
The last scheduled game in the 2017-2018 season is February 25, 2018. Hopefully the team then plays much further into March. The deadline to declare for the NBA draft is April 22, 2018.
The "early period" NCAA basketball signing window is November 8-15, 2017 while the "regular period" is April 11 to May 16, 2018.
To the extent Herro wanted to wait until the middle/end of the later signing window, it could open up a spot... but that's one hell of a risk for a kid to take.
