On March 30, 2007, in their hometown of Detroit, Shelley and Sabin made their ROH debut as a team under the name The Murder City Machine Guns by challenging and then attacking Jay Briscoe after he and his brother Mark, who had injured himself during the match, had won back the ROH World Tag Team Championship from Naruki Doi and Shingo.
On April 28 in Chicago, IL, at Good Times, Great Memories The Briscoe Brothers successfully defended their tag team title against Shelley and Sabin.

In April 2008 Shelley and Sabin returned to Ring of Honor, losing to the Age of the Fall (Tyler Black and Jimmy Jacobs) and defeating the Briscoe Brothers on the 18th and 19th respectively.
