Kuehl is ok but he´s no NBA material. He played for North Carolina in 96/97 and even had a good game at the portsmouth invitational pre draft tourney. He did play for a couple of good european teams like Aris Saloniki and CSP Limoges. He signed with Ludwigsburg of the german bundesliga before the 2003/2004 season but never played. I don´t know what happened to him.
He´s definitly big and strong, but that´s it.
Here is an old profile, couldn´t find anything newer.
