GEORGETOWN — Pick your favorite Hollywood or real backup quarterback story — “Varsity Blues,” “Any Given Sunday,” Frank Reich in 1993, Kurt Warner in 1999 — and Noah Booras’ is up there with the best. Becoming Georgetown’s quarterback in Week 4 last fall after a season-ending injury to the starter, Booras went on a tear the rest of the season, throwing for 2,810 yards and 33 touchdowns while helping the Eagles earn a district title, a spot in the third round of the playoffs and a 10-3 record.
