BUFFALO, N.Y. - Challenging as it will be to replace coach Turner Gill at Buffalo, athletic director Warde Manuel knew this day would inevitably come.

What makes Manuel's job easier in finding a qualified successor, after Gill accepted an offer to coach at Kansas this weekend, is the remarkable job Gill did in bringing respectability to what had been one of nation's most laughable football programs.

The proof was evident Sunday.

In the 12 hours since word leaked regarding Gill's departure, Manuel said he's received more inquiries from what he described as "quality" candidates than he did throughout his previous search in 2005, when he took a shot on Gill, a first-time coach, for a job very few expressed much interest in.

"I just have to feel that I won't get hung up as much or at all compared to where I was last time. It's a different job now," Manuel said during a press conference to discuss Gill's departure and Buffalo's plans to launch a national search for his successor. "Turner Gill has left this place much better than when he found it. For that I will forever be grateful."

The Bulls were transformed in four seasons under Gill. In finishing with a 20-30 record, he led Buffalo to its first Mid-American Conference championship last year, and took the Bulls to their first bowl game, a 38-20 loss to Connecticut in the International Bowl.

That's a remarkable turnaround for a team that, before Gill's arrival, went 10-69 since joining the MAC in 1999.

"He has brought Buffalo in a four-year period to places that I didn't expect so quickly," said Manuel, who wished Gill well at Kansas. "We'll miss all of that. But we will move on."

As his first step, Manuel named Bulls offensive coordinator Danny Barrett interim coach, and noted that the former Canadian Football League star quarterback is considered a candidate to take over the job on a full-time basis.

Though he declined to provide a timetable for the search, Manuel said he hopes to have it completed before the end of the bowl season, which runs through the BCS national championship Jan. 7.
