With the Buffalo Bills having lost out on Bill Polian as a potential personnel boss and coach Doug Marrone opting out of his contract, the AFC East franchise is counting on general manager Doug Whaley to lead their coaching search.

The Bills are expected to interview San Diego Chargers offensive coordinator Frank Reich, Bills defensive coordinator Jim Schwartz and former New York Jets coach Rex Ryan and Denver Broncos offensive coordinator Adam Gase.

Gase is up first.

Reich and Schwartz are among the top candidates.
