After just 24 hours on the job, Jon Tenuta has changed his mind. He won't join Tim Beckman's new Illinois staff, where he was expected to be defensive coordinator. He will remain at at North Carolina State for family reasons, the 31-year veteran assistant said Wednesday.

 ``Illinois is a great program and I think the world of Tim Beckman,'' Tenuta said in a statement released by Illinois. ``I've known Beck for 20 years and I have no doubt that with the staff he is putting together, he will have Illinois at the top of the Big Ten very soon.

``However, my family comes first and I may have made a decision without fully thinking through the situation with them. My son is a senior in high school and has signed a letter of intent to play baseball at N.C. State, and it is something I just don't want to miss. I was one of the first people to contact Beck and congratulate him on the opportunity at Illinois, and I wish him and the Illini nothing but the best.''

Tenuta's change of heart leaves Beckman with four unfilled slots on his staff.

The odd part about this is that Beckman said at various times last month that he either had his whole staff, or all but one assistant, lined up. He was merely waiting for the new staffers to finish up the bowl games of their current teams, he said. 

Luke Butkus, who will be offensive line coach, and Chris Beatty, who also will be on the offensive staff, were announced Tuesday along with Tenuta.

Butkus, the nephew of Dick Butkus, is young for an offensive-line coach, but has paid his dues. A three-year starter who finished his career at Illinois in the Sugar Bowl in 2001, he has been a Seatlle Seahawks quality control assistant the last two years. Before that, he was an assistant offensive line coach for three seasons with the Bears.

Beatty is leaving Vanderbilt, where he was wide receivers coach and offensive recruiting coordinator this season. Beatty also has been an assistant at West Virginia (2008-2010), Northern Illinois (2007) and Hampton (2006).

Previously named to Beckman's staff: Keith Gilmore, defensive line coach, who's staying on at Illinois; and two of Beckman's former Toledo assistants, Alex Golesh, who will be an offensive assistant and recruiting coordinator, and longtime Beckman associate Mike Ward, who will be a defensive assistant.

Beckman is leaving the specific position/coordinator assignments of assistants open until he has his whole staff assembled.
