Boston College quarterback Thomas Castellanos didn't spend too much time celebrating his team's upset victory over No. 10 Florida State on Monday night, as he needed to prepare for classes on Tuesday.

"I go to Boston College, so we got class tomorrow," Castellanos said when asked about his week following the game.

The 21-year-old excelled through the air and on the ground during Boston College's 28-13 win over Florida State, handing the Seminoles their second consecutive loss to begin the 2024 season.

Castellanos completed 10 of his 16 pass attempts for 106 yards and two touchdowns. He also added a third score as a runner, picking up 73 yards on 14 attempts. The Eagles dominated the Seminoles' front seven, recording 263 rush yards as a team and controlling the clock throughout the duration of the contest.

Boston College's defense also made a strong impression, as Florida State signal-caller DJ Uiagalelei was sacked three times and threw an interception near the start of the second half.

The Eagles got off to a commendable start under new head coach Bill O'Brien. The former Houston Texans head coach and New England Patriots offensive coordinator was hired by the school on Feb. 9 after he initially joined Ohio State as the Buckeyes' offensive coordinator.

"I'm very proud of these guys," O'Brien said after Monday's win, per Bob Ferrante of the Associated Press. "They were resilient tonight. To come down here against a team that really in their minds had to have this win, that's a heck of a statement for BC. But it's just one win."

Castellanos and the Eagles will attempt to start the season 2-0 as they face off against Duquesne on Saturday at 3:30 p.m. ET.
