Not even their Week 3 Bye could help out Oakland.  Despite jumping out to a 21-3 lead and going into halftime ahead 21-10, and despite a touchdown by linebacker Sam Williams and two interceptions by cornerback Nnamdi Asomugha, the Raiders failed to shut down the Browns' offense, allowing 14 third quarter points.  In the days after the game, coach Art Shell said that Raider higher-ups responsible for deciding whether or not a challenge is worthwhile told him that one was not following a third and 16 play from the Cleveland Browns' 45-yard-line that went for fifteen yards in the fourth quarter.  Shell said that after reviewing the telecast of the game, "I was miffed, because we should have challenged it." Following that, a fourth and 1 hand-off to LaMont Jordan was stopped in the backfield for a loss of two, resulting in a turnover on downs.. How many more points did Oakland have at halftime relative to the Browns?
