What position he plays in college remains to be seen, but Costanzo is getting attention for both sides of the ball.
An offensive guard and a defensive tackle, Costanzo also dabbles in special teams, doing the longsnapping for Monte Vista.
"Wherever they need me, I'll play. I'll probably end up at guard, but I could play on either side of the ball. I'll be able to show more on offense this year," said Costanzo.
He is still awaiting his first offer, and will do the camp circuit this spring and summer to get more exposure.
Costanzo will be at the Nike Camp at Stanford as well as a team camp at USC.
As for a childhood favorite, Costanzo picked a Big 12 school. "I'd say it was Nebraska. My dad went there," said Costanzo.
Costanzo said he would like to take all of his visits, and his goal is to be selected to the Army All-American Game where he hopes to announce his decision.
He has a 2.8 GPA and will take his SAT in the spring.
