Background and College
Born August 23, 1984 in West Point, New York, Kapinos was named All-Met at West Springfield High School, in Springfield, Virginia, where his coach was former Green Bay Packers punter Bill Renner. He then attended Penn State where he was a Ray Guy Award finalist and a third-team All-America selection by the Associated Press. He is the Nittany Lions' all-time leader in punting yardage.
As a Jet
He signed as an undrafted free agent with the Jets following the 2007 NFL Draft but was released during the preseason. Later in the 2007 season the Baltimore Ravens employed the left-footed Kapinos to help prepare for left-footed punter Donnie Jones prior to their week 6 game versus the St. Louis Rams. On November 27, Kapinos was re-signed to the Jets' practice squad. He was promoted to the active roster on December 22 when wide receiver Laveranues Coles was placed on injured reserve. He saw his first regular season action that week against the Titans, punting five times for 208 yards, including two punts inside the 20. Kapinos was then placed on the inactive list for the last game of the season. After a well-publicized 2008 offseason competition with Ben Graham, the Jets released him on June 10, 2008.
After the Jets
Kapinos signed a two-year deal with the Green Bay Packers on December 3, 2008 to replace released punter Derrick Frost.
