Kyle Shanahan isn’t the only Redskins coordinator who could draw interest in the coming weeks for NFL head coaching jobs. Defensive coordinator Jim Haslett also could be in the mix.

According to a person with knowledge of the league’s coaching market, at least two teams with coaching vacancies have preliminary interest in Haslett. The person spoke on the condition of anonymity because he was not authorized to discuss the matter publicly, and did not identify the teams.

It is not clear if the interest will lead to Haslett being interviewed for any head coaching jobs or if he will end up being a serious contender such an opening this offseason. Some people within the league seem convinced that both Haslett and Shanahan, the Redskins’ offensive coordinator and the son of Coach Mike Shanahan, will draw some interest but are long shots to be offered any head coaching jobs this offseason.

Mike Shanahan was asked at his news conference Monday about head coaching opportunities for Kyle Shanahan and said it was his feeling that “it’s not time to interview during the season.”

The Redskins will host the Seattle Seahawks in a first-round NFC playoff game Sunday. If the Redskins win and advance to a conference semifinal the following weekend, their assistant coaches would be eligible, under NFL rules, to interview for head coaching jobs next week with the Redskins’ permission. Redskins assistants are not eligible to interview for head coaching jobs this week because the team is playing in the opening round of the playoffs.

Under NFL rules, assistants on teams with first-round playoff byes can interview this week for head coaching jobs. Assistants on teams whose seasons have ended are eligible to interview at any time. Seven NFL teams fired their head coaches Monday and have begun lining up interviews with candidates.

Haslett, the former head coach of the New Orleans Saints and former interim head coach of the St. Louis Rams, oversaw a Redskins defense that struggled mightily at times this season, particularly early on. There even were some calls around midseason for Haslett to be ousted. But Mike Shanahan stuck with him, and Haslett earned praise for holding together a defense that ended up making significant contributions to the Redskins’ current seven-game winning streak.
