"Cosmo," as he was known to his teammates, was one of the fiercest members of the Penn offense from 1984-86.  He burst onto the Penn football scene in 1984 against Dartmouth, where he gained 105 yards in his first collegiate game.  He finished the season as the team's leading rusher with 596 yards, averaging 66.2 per game.  He also recorded seven touchdowns and played in all but one game that year en route to the Ivy League's Rookie of the Year award.


As a junior, Comizio continued his offensive onslaught, leading the team with 779 rushing yards and five touchdowns.  He was also the team's second-leading receiver with 18 catches for 208 yards.  Among all Ivy Leaguers, he was the second-leading rusher.  For his gridiron accomplishments, Comizio earned a Second-Team All-Ivy League nod.


Prior to the start of the 1986 season, Comizio was named a preseason I-AA All-American by The Sporting News.  During the course of his senior season, he proved that the honor was well deserved. For the third consecutive year Comizio led the Red and Blue in rushing, recording 1,104 yards and setting a then-program record in the process, becoming the first back in Penn history to rush for more than 1,000 yards in a single season.  Comizio also threw his first career pass against Brown for a six-yard touchdown.


Comizio was the third-straight member of the Red and Blue to receive the Asa A. Bushnell Cup in 1986, as the Ancient Eight’s Most Valuable Player.  


Beyond the football field, Comizio was a GTE Academic All-American.  He was also a recipient of the Class of '15 award given to the male senior that most closely approaches the ideal University of Pennsylvania student-athlete.
