When IU was recruiting both Kaufman and Furst they didn't want to play together. Now that Furst has committed to Purdue it is apparently no longer an issue. However, since Lander committed to IU, he is now the one Kaufman doesn't want to play with. Strange, eh? 🙄
I'd take these comments about one player not wanting to play with another with a giant grain of salt unless it comes directly from the player or someone who would definitely know (immediate family, coach, etc). These rumors likely come from disgruntled IU fans or Purdue fans.
