Jack Burkman, head of the Washington, D.C. lobbying firm J.M. Burkman & Assoc. who is seeking to ban gays from the NFL, says he intends to build a national coalition to boycott any football franchise that picks openly gay football player Michael Sam in the NFL Draft, which starts Thursday at Radio City Music Hall in New York City.

In a release issued Thursday, Burkman said he would "leverage his political clout" to ensure that the franchise that selects the 6-foot-2, 260-pound defensive end from Missouri would get "roughed up financially."

"We shall exercise our First Amendment rights and shall not stop until the drafting NFL franchise cannot sell a single ticket, jersey or autographed football," said Burkman. "In short, we shall be relentless."

Burkman claims in the release that he is currently mobilizing "powerful grassroots organizations in 27 of the 50 states," as well as a "coalition of Evangelical Christian leaders from across the nation to take part in a protest if Sam is drafted."

"The NFL, like most of the rest of American business, is about to learn that when you trample the Christian community and Christian values there will be a terrible financial price to pay," said Burkman.
