HATTIESBURG, Miss. (AP) -- Joe Southwick threw for three touchdowns and Boise State took advantage of five turnovers to breeze past Southern Mississippi 40-14 Saturday.
The Broncos (4-1) won their fourth straight by intercepting Golden Eagles quarterback Ricky Lloyd twice and recovering three of four fumbles by Southern Miss, which is 0-5 for the first time since 1976.
The first interception came on Lloyd's fifth attempt of the game and set up Southwick's 11-yard scoring pass to Matt Miller that put the Broncos on top 7-0.
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.
