One of the many things SB Nation's new production team has been up to is working with Pittsburgh Steelers safety Ryan Clark on an episode for a new series called The Core of Sports. Clark, who wears the No. 21 during every practice to honor former slain Redskins teammate Sean Taylor, has come a long, long way since joining the NFL as an undrafted free agent rookie out of LSU. More than a decade later playing safety in the NFL, Clark made his first Pro Bowl in 2011.

Clark, unsurprisingly, was incredible hard-working and great to work with. Even after a long day in the early spring Arizona heat, Clark apparently was always down for one more shoot, and he was a great interview and interesting, agreeable guy throughout the process.
