When we get into league, we are going to dominate. We just have to play smart. We just made too many mistakes. If you take those away, we could have won this game.” Knox, who rushed for 106 yards on 15 carries, helped Birmingham stay in contention in the first half with two first-half touchdowns. Knox scored on a 48-yard touchdown run in the first quarter for a 7-0 lead and caught a 49-yard touchdown pass in the final minute of the first half for a 21-18 lead. Birmingham junior James Beloff completed 11 of 24 passes for 203 yards and a touchdown before leaving the game in the fourth quarter after being sacked for the third time. Trailing 21-18, Dorsey quickly bounced back in the second half, scoring 21 points in the first 5:11 of the third quarter to take a 39-21 lead. Dorsey (4-1) scored the final 28 points of the game with the help of Birmingham miscues after trailing 21-18 at halftime to turn the rematch of the 2004 City final into a rout.
