A look at who Lions might talk to this week

At noon Monday, the Detroit Lions' coaching search will officially hit its second week, with some candidates already off the board and others available to talk for the first time.

“We will go through the process,” Lions team president Tom Lewand said when he and Martin Mayhew announced they had fired Jim Schwartz last Monday. “I think going through a thorough process is extremely important.

“That doesn’t necessarily mean that has to be a long process, but it has to be a thorough process.”

Baltimore offensive coordinator Jim Caldwell already interviewed and is the only known candidate to formally do so. John Wooten, the chairman of the Fritz Pollard Alliance Foundation, told ESPN.com last week that Caldwell was told the Lions would get back to him in a few days after his Friday interview.

Now starting its second week, much of the focus will begin with San Diego offensive coordinator Ken Whisenhunt, who is a candidate for some of the five current NFL openings.

While requests to talk with coaches have yet to go out or be made official, here are some of the candidates the Lions might target:

Ken Whisenhunt, San Diego offensive coordinator: It would be beyond stunning if Whisenhunt did not interview with the Lions this week. ESPN Insider Adam Schefter reported Sunday it is essentially his job to lose, which makes sense considering he fits all of the qualities Detroit is looking for in its next coach. The downside for Whisenhunt is the Lions cannot hire him for at least another week, as they can’t make an official move -- if they choose to do so -- until San Diego is out of the playoffs. But they can at least chat with him this week if they would prefer.

Jay Gruden, Cincinnati offensive coordinator: Schefter mentioned him as someone Detroit would likely want to talk with as well, as he has played a major role in developing quarterback Andy Dalton (and you can argue whether that is good or bad after his performance Sunday, but he has been a very good regular-season quarterback). He has also been a head coach before in the AFL and UFL and was successful there. Another thing to watch with Gruden is his ties to agent Bob LaMonte, who also lists Detroit senior personnel executive Brian Xanders among his clients.

Greg Roman, San Francisco offensive coordinator: Like Whisenhunt, if the Lions want to talk to Roman, they can talk, but not hire since San Francisco is still in the playoffs. His name has not come up as much as Whisenhunt and Gruden, but he has been a head coaching candidate before and he has developed a dynamic offense with the 49ers. It is unknown how much Roman really helped develop Colin Kaepernick, though, as he has a bevy of coaches with quarterback experience in San Francisco, including Jim Harbaugh, quarterbacks coach Geep Chryst and offensive assistant Ronald Curry. He has coached David Carr, Andrew Luck and Kaepernick, though.

Mike Zimmer, Cincinnati defensive coordinator: He isn’t an offensive coach and he does not have head coaching experience, but Zimmer led one of the top-ranked defenses in the NFL and has been a defensive coordinator since 2000. He’s also been close in the past, interviewing for the Cleveland job last season. In Mayhew’s news conference to discuss firing Schwartz, he mentioned that an offensive coach wasn’t a dealbreaker for the Lions, but that whomever the team hired would have to bring in someone to work with Matthew Stafford. If Zimmer gets an interview, that would have to be a strong part of his presentation to truly be considered.

Other names that might get a look: Cincinnati assistant and former Raiders head coach Hue Jackson; Arizona defensive coordinator Todd Bowles.
