Erie County’s recent call for outside counsel in stadium lease negotiations with the Buffalo Bills drew bids from 13 firms with ties to western New York, most of which offered experience in municipal law and public finance, construction and real estate, and a handful have handled professional sport stadium leases.

The firms also offered discounted rates, said Erie County Attorney Michael Siragusa. Lawyers involved in the bidding said in interviews they offered discounts from 10 percent to 25 percent.
