The Bears lack of success on defense would have scared away most from pursuing Blache, but a rash of injuries were certainly to blame for the team being the top scoring defense in football a year ago to 25th in 2002.
Commissioner Paul Tagliabue recently suggested any team hiring a head coach should consider minority candidates.
The 49ers were trying to woo Monte Kiffin, but the Bucs defensive coordinator signed a new three-year contract to stay in Tampa.
Still, GM Terry Donahue wants a defensive coach in mind as some of the coaches on the offensive side of the ball could remain with the team.
If Blache were to be hired by the 49ers it would leave the Bears scrambling to find a replacement. The team has yet to fill the hole left by former defensive line coach Rex Norris and would have to expand their search to find a defensive coordinator.
There is also a chance Donahue, who has head coaching experience, might take the job for the season in order to get the coach he wants in place for the 2004 season.
