MM and Barrows both are reporting that Mike Singletary and Scott McCloughan interviewed "current" Browns QB coach Rip Scherer. I put it in quotations because it sounds like Eric Mangini is unlikely to retain him.
As Barrows and Maiocco have both intimated, it's especially interesting given the fact that Singletary said in his end of season press conference that the new offensive coordinator would have the discretion for hiring his own quarterbacks coach. Does this mean Rob Chudzinski is the front runner?
It's also possible that this is part of the due diligence. Maybe Singletary thinks that whomever the new OC would want to bring in as QB coach reflects on that person's abilities as OC. If so, it would make sense to find out who the OC candidates want as their QB coach and do the interviews as a package deal.
Here's Scherer's coaching background:

1986 Georgia Tech, quarterbacks coach/offensive coordinator
1987 University of Alabama, offensive coordinator
1988-90 University of Arizona, offensive coordinator/director of football operations (1988)
1991-94 James Madison University, head coach
