Write a question about the following article: Hoping to add to a six-game winning streak, the Broncos returned home for an interconference duel with the Tampa Bay Buccaneers. The Broncos grabbed the early lead, when defensive tackle Mitch Unrein, lining up as a fullback, caught a 1-yard touchdown pass from quarterback Peyton Manning. The Buccaneers responded, with a 31-yard field goal by placekicker Connor Barth, then grabbed the lead at the end of the first quarter, with quarterback Josh Freeman connecting on an 11-yard touchdown pass to tight end Dallas Clark. After a scoreless second quarter, the Broncos re-claimed the lead for good with 21 unanswered points, consisting of two Manning touchdown passes to wide receiver Demaryius Thomas&#8212;from 8 and 10 yards, followed by linebacker Von Miller returning an interception off Freeman 26 yards for a touchdown. After a Manning interception late in the third quarter, a 50-yard field goal by Barth to begin the fourth quarter narrowed the gap to 28-13, but the Broncos countered with a 31-yard field goal by placekicker Matt Prater. With 4:37 remaining in the game, the Buccaneers tried to rally, with a 55-yard field goal by Barth, followed by a 5-yard touchdown pass from Freeman to wide receiver Mike Williams with 2:39 remaining. However, the Buccaneers' onside kick attempt was unsuccessful, and the Broncos subsequently ran out the clock. With the win, the Broncos exceeded their win total from 2011, and also clinched their second consecutive AFC West division title. This was the 12th division title in the Broncos' franchise history, tying the Oakland Raiders for the all-time lead in AFC West championships since the 1970 AFL-NFL merger. The Broncos also clinched consecutive division titles for the first time since 1986-87.
