CLEMSON There appears little question as to whether Clemson offensive coordinator Rob Spence will entertain other job offers.
Discerning why, as well as what it would take for Spence to leave the Tigers, remain the clues to unlocking this mad scientist mystery.
Hours after Clemson concluded its final pre-bowl campus practice Friday morning, Spence flew to Knoxville, Tenn., to interview for Tennessee's vacant coordinator job.
"I'd say anytime you go, it's serious," coach Tommy Bowden said. "It's like Rich (Rodriguez) flying up to Toledo to meet with (Michigan officials recently) anytime you make the trip, it's pretty serious when you go see somebody."
Bowden dismissed immediate concern because regardless of the outcome, he said Spence will serve as play-caller for the Dec. 31 Chick-fil-A Bowl against No. 22 Auburn.
Yet if Spence does not get the job whether offered or not bigger questions figure to be raised, especially within the program, about why he continues to explore other comparable opportunities.
Clemson's third-year coordinator made for an attractive target after last season, especially with Bowden's future perhaps in limbo.
He reciprocated that interest in two of three instances, lending serious consideration to becoming Minnesota's coordinator under their new coach, close friend Tim Brewster.
Spence turned down a three-year offer at a salary of nearly $325,000, considerably higher than the $207,000 he was to earn this season.
He subsequently visited with the NFL's Oakland Raiders about a staff position as well.
Before those came about, Alabama coach Nick Saban sought out Spence and offered to double his salary to be the Crimson Tide's coordinator, but Spence displayed no interest.
Now knocks Tennessee, which was to pay David Cutcliffe $340,000 this past season. Coach Philip Fulmer was granted permission from Bowden earlier this week to speak with Spence, reportedly the first candidate to interview for the job.
Bowden intimated that he does not take Spence's pursuits personally.
"That's just the nature of the profession," Bowden said. "I just look at is as going to a place where you're comfortable. Everybody goes where they're comfortable. Environment, geography, style of play, close to home. I see it as a little bit different."
Spence, whose experience working for a program in a BCS conference is otherwise limited to four years as a Maryland position coach (1992-96), has spoken numerous times this year of the immense pressure and scrutiny Tigers coaches and players endure on a daily basis.
One microscope under which Spence has never appeared comfortable was evident again Friday.
Spence uncharacteristically hopped an administrative assistant's car outside the practice field gates and rode to the locker room after the morning workout, presumably to bypass the routine interview areas where media members camp out.
When it did not work, Spence answered the first question about Tennessee's interest with a comment on the quality of practice.
He responded to the next question by saying, "I am flattered that they called," then deflected further questions by entering the staff locker room and saying he needed to prepare for a recruiting meeting.
Bowden declined to declare whether receivers coach Dabo Swinney would be promoted to coordinator if Spence left, as was the expectation a year ago.
"I'll address that if and when it happens," Bowden said.
Bowden said no other programs have contacted him regarding Clemson assistants, although that could change after bowl season. Linebackers coaches David Blackwell and Ron West have personal ties to Rodriguez and would be logical candidates for the Michigan staff.
