The Bills, who are looking to fill the vacancy left by Doug Marrone following his exercising of an opt-out clause in his contract, have also requested interviews with the 49ers' Greg Roman and Eagles' Pat Shurmur, according to Schefter.

It shouldn't be much of a surprise to see Shanahan has potential suitors with an opening at head coach, especially among teams leaning toward the offensive-minded. Having served seven seasons with three different NFL teams as offensive coordinator, the younger Shanahan, 35, has had notable success at every stop when given competent quarterback play.

With Cleveland, Shanahan implemented his zone-blocking scheme early and effectively, and it wasn't until the devastating loss of center Alex Mack that both the running game began to suffer and Brian Hoyer's play deflated.

Shanahan has already done enough at this level to warrant teams in need of a head coach to take a long, hard look at him, but it would be best for the Browns if he ultimately stays in Cleveland.
