I agree, Turbine. Without his marked improvement as a senior, Tyren isn't getting paid to play anywhere this next season. Belgium is a good place for him to grow and mature for at least a year.
As for Gradnigo, be the top offensive option for mid-major with a proven coach or sit out one year and have to start all over again in a new program with only one season to play? Seemed like an easy choice from the outside looking in, granted he needed to do whatever he felt was best for himself.
