Brandon delivered what was said to be a persuasive presentation about why Shanahan should be interested in the Bills. He pitched Shanahan on the merits of the market, the condition of the franchise and what a good match it could be.
The two sides did agree on one point: Each would take its time in this process, to be certain it makes the right decision about what's next for each.
"We had an excellent meeting," Shanahan said Wednesday. "I was really impressed with Russ Brandon and everything he had to say. We're going to stay in touch and see what develops."
The Bills want to thoroughly investigate all of the coaches who are and could be available, even though they clearly are serious about Shanahan.
At the same time, Shanahan would like to see what opportunities might be out there for him to return to the NFL in 2010.
The Bills fired Dick Jauron last week and named defensive coordinator Perry Fewell interim coach.
