MIAMI, Fla. (AP) — Who Dat won the Super Bowl? The New Orleans Saints, that’s who. Ain’t kidding. Put away those paper bags forever: Drew Brees and the Saints are NFL champions, rallying to upset Peyton Manning and the Indianapolis Colts 31-17 Sunday night in one of pro football’s most thrilling title games. Brees tied a Super Bowl record with 32 completions, the last a 2-yard slant to Jeremy Shockey for the winning points with 5:42 remaining. The Pro Bowl quarterback was chosen Super Bowl MVP. ‘‘We just believed in ourselves and we knew that we had an entire city and maybe an entire country behind us,’’ Brees said. ‘‘What can I say? I tried to imagine what this moment would be like for a long time and it’s better than expected.’’ A surprise onside kick sparked the Saints’ second-half comeback. Their 25th-ranked defense made several key stops, and Tracy Porter’s 74-yard interception return on a pass from Manning, of all people, clinched it.
