The only male two-sport athlete on Temple's campus - he walked on to the baseball team as an outfielder last spring - Reilly's trip has been an improbable one.
When roommate Chris Coyer was replaced at quarterback in the final two games last season by Clinton Granger, it was assumed that new coach Matt Rhule, who is moving the team away from its ground-and-pound running style to a pro-style offense, would be likely to go with Granger this season.
But Rhule, who took over in December, announced that there would be open competition for the starting quarterback's job in the spring.
With the decision already made to move Coyer to H-back, both Reilly and Granger were impressive in the Cherry and White game. Reilly led the White to a 34-28 victory, completing 25 of 41 passes for 366 yards and four touchdowns while throwing just one interception.
Granger, however, looked equally at ease, throwing for 302 yards (26 of 44), three TDs and an interception.
Rhule felt comfortable enough then to install Reilly atop the depth chart. However it's clear that this is not etched in stone.
"Connor has never taken a snap, and I am going to put a lot of pressure on Connor this fall to see if he is the guy," said Rhule, adding that Granger is still in the mix for the job. "But at the end of the day, I think he has a unique perspective. He has been on the headsets - he has heard us cussing each other out - he has heard the chaos, and I think he's prepared for that.
Rhule, who will helm a pro-set offense, pointed to the success that first-year NFL quarterbacks such as Washington's Robert Griffin III and Seattle's Russell Wilson experienced as rookies last season playing in systems that fit their skills.
"Last year in the NFL they proved that first-year guys, if they are in the right system, can be successful,' said Rhule, who spent last season as an offensive line coach with the New York Giants. "We expect him to be successful or whoever is the quarterback in our system."
Said Reilly: "I've played quarterback all my life. The only thing that changes, again, is the speed of the game. I felt comfortable in our system, and I feel like I'm pretty comfortable in the offense. I feel really good with the opportunity."
