Now, he's raised his scores and moved himself into the top band, a status that has made him an attractive option for Penn, Yale, Dartmouth and Brown.
Shanbour transferred from Bishop McGuinness to Heritage Hall at the start of is junior year and had to miss that season.
As a senior, he threw for 2,612 yards and 37 touchdowns while throwing just three interceptions in helping the Chargers to the Class 3A semifinals.
But with Sterling Shepard as his top target and Barry J. Sanders in the backfield, Shanbour's accomplishments were sometimes attributed to the players around him.
“I love those guys to death, but a lot of people thought it was all them,” Shanbour said. I wanted to show people that I was doing the things I needed to to play in college.”
In January, Shanbour will head back to Connecticut to finish the year. He's hoping to get an age waiver so he can play baseball (he recently turned 20), but if not, he'll coach Choate's junior varsity team in the spring.
Either way, Shanbour plans to get into coaching, likely in football, whenever his playing career ends.
