CBS Sports has evaluated each of the 120 FBS coaches' seats, and as you might expect, there's a wide range of temperatures throughout the conference.
CBS rates the coaches on a scale of 0-5, with a five being firmly on the hot seat. "It's time to win now," they write. Those with ratings of zero are untouchable.
Anything above four is "feeling the pressure." Those above three are "on the bubble." If a coaches' rating is two or above, he's safe, and a one or above means a change is "highly unlikely."
Here's how the 10 coaches stack up.
Paul Wulff, Washington State (5.0)
Washington State has won just three games (and one in conference) in two seasons under Wulff, and at times looked hapless. His 22 losses make it hard to raise much of an argument with his status. He's one of just four coaches with the unfavorable 5.0 rating and the only one above 4.0 in the Pac-10.
Dennis Erickson, Arizona State (3.5)
Only Maryland's Ralph Friedgen has a higher rating and a winning record, but Erickson's 19-18 record in three seasons is bolstered by a 10-win season in year one. The Sun Devils have finished sixth and ninth in the Pac-10 in the past two seasons.
Lane Kiffin, Southern Cal (3.0)
The Kiffin Era has yet to begin, but winning and keeping his name out of the headlines for anything off-the-field could help his number go down.
Mike Stoops, Arizona (2.0)
Other than a bowl game he'd like to forget, 2009 was another step in the right direction for Stoops. He's improved his record in conference play consistently since taking the job before the 2004 season and tied for second in the league last year.
Jeff Tedford, Cal (2.0)
Tedford's Bears shared the 2006 Pac-10 title, and in eight seasons, he still has yet to finish with a losing season -- or even a .500 season -- in Berkeley.
Rick Neuheisel, UCLA (2.0)
The Bruins conference record didn't improve in Neuheisel's second season, but UCLA still won seven games, including a win over Temple in the EagleBank Bowl.
Chip Kelly, Oregon (1.0)
Kelly has had to weather plenty of non-football troubles in just his first season as Ducks' head coach, but if you knock the Trojans off their perch in just your first season, it's going to take a lot before you're no longer welcome.
Jim Harbaugh, Stanford (0.5)
Harbaugh's proven to be the real "deal," improving in each of his three seasons as Cardinal coach. Shooing away numerous offseason suitors is a nice way to inspire good faith, too. But Stanford fans wanting more seasons like the last -- and perhaps, better -- might want to keep cheering Rich Rodriguez's every move.
Steve Sarkisian, Washington (0.5)
The Huskies have plenty of hype and a big-time quarterback. Sarkisian helped Washington take a huge step in 2009, and finished with satisfying wins over Cal and in the Apple Cup. But no one has to tell him that 5-7 won't cut it in the big picture for very long. Step two begins this fall, and he'll get an early chance to prove himself again in a nonconference matchup with Nebraska.
Mike Riley, Oregon State (0)
Hometown coach. Thirty-six wins in the past four seasons, including a 3-1 record in bowls and a couple wins over USC? Riley's roots are far from danger.
