Illinois football coach Tim Beckman has filled all but one position on his coaching staff, he said during a radio interview Saturday, but announcements on the hires were expected to be delayed because the incoming coaches were busy working with their current teams during bowl game preparations.   The Toledo Blade reported Toledo assistants Louis Ayeni, Alex Golesh and Mike Ward were offered positions with the Illini by Beckman.   Ayeni serves as the Toledo associate head coach and run game coordinator while Golesh coaches tight ends and works as recruiting coordinator while Ward is assistant head coach, co-defensive coordinator and linebackers coach.   Wyoming offensive coordinator Gregg Brandon is a prominent name mentioned for a similar post with the Illini, but Beckman offered no specifics during the interview on WDWS radio in Champaign. Brandon is a former head coach Bowling Green, where Beckman served as one of his assistants. Brandon was busy working Saturday during the New Mexico Bowl.   "They can't afford to be exposed,'' said Illinois athletic director Mike Thomas about the hires.   In the Toledo Blade report, Rockets coach Matt Campbell said the plan was to have all of the assistant coaches remain at Toledo through the team's appearance in the Military Bowl on Dec. 28.   The school announced last week that it retained defensive line coach Keith Gilmore, but defensive coordinator Vic Koenning turned down an offer to remain with the program after serving as the interim head coach when Illinois plays UCLA in the Kraft Fight Hunger Bowl on Dec. 31.   Illinois had won an appeal with the NCAA to have two coaching staffs in place. One would coach the bowl game and the other would begin recruiting and other preparations for next season under Beckman.   John Supinie can be reached at Johnsupinie@aol.com.
