After he was picked, Sam famously kissed his boyfriend, fellow Missouri alumnus Vito Cammisano, on live television. Even President Barack Obama congratulated Sam and the Rams "for taking an important step forward in our nation's journey".
Yet a week ago the Rams dropped the rookie player as they cut their squad roster from 75 to 53 players. Last Thursday the Cowboys added him to their 10-man practice squad, with the chance of a place in the main squad if he performed well in training.
The American football writer Peter King, speaking on NBC, claimed the NFL had avoided a "nightmare situation" when Sam was added by the Cowboys.
However, the Cowboys' owner, Jerry Jones, told the Texan sports station 105.3 The Fan that the team had not spoken to NFL officials about signing Sam, and that it was "his availability, his position and his high motor" that led to his signing.
Burkman said that by signing Sam, Jones had "betrayed American values, Christian values, and his own city's values. The people of Dallas - and Christians all across this land - are about to make him pay a huge financial price. The Cowboys are no longer America's team."
The replica Rams jersey that bears Sam's name quickly became the sixth most popular in the NFL; pop star Harry Styles wore one at a One Direction gig in Missouri last month.
