The lead swelled to 24-0 at the half when Southwick threw his second touchdown, a 33-yard strike to Chris Potter with 6 seconds left in the second quarter.
Southwick completed 17 of 26 passes for 201 yards with an interception.
D.J. Harper led the Broncos in rushing with 14 carries for 51 yards, including touchdown runs of 11 and 19 yards.
