TAMPA — Chamberlain used a 23-point explosion in the second quarter to win its preseason game.
The Chiefs' attack in the first half was fueled largely by their ground game with junior running back Xavier Johnson running for 168 yards and two touchdowns in only one half of work.
East Bay finally scored late in the third quarter with a two-play, 57-yard drive capped by an 8-yard touchdown run by senior running back Quantavious Gibbs.
But Chamberlain quickly responded with another score on a 30-yard quarterback draw by junior Ronnie Scott.
Though his Chiefs are a young team, with only a couple of seniors on offense, coach Joe Severino said he feels strongly that his team can compete for a championship in Class 7A, District 7. The district also includes Freedom, Gaither, Steinbrenner, Tampa Bay Tech and Wiregrass Ranch.
"I truly feel like the district is open," Severino said. "I felt like with a bounce here or there, we could have been competing for districts last year."
