Last playoff appearance: 2011 (lost in divisional round)
Longest playoff drought: 9 seasons (2002-10)
Other notable droughts: The Texans are 0-5 against the Baltimore Ravens, the team they lost to in last year's postseason.
The good: They'll repeat as division champions if: Newcomers Whitney Mercilus and Bradie James make up for the departures of Mario Williams and DeMeco Ryans on the defense.
The bad: They'll make an early playoff exit if: The right side of the offensive line, which has two new starters in Antoine Caldwell and Derek Newton, breaks down.
Last playoff appearance: 2008 (lost in divisional round)
Longest playoff drought: 8 seasons (1970-77)
Other notable droughts: The Titans had two shutouts in the 2000 season, but none since then.
The good: They'll challenge the Texans if: Second-year quarterback Jake Locker is ready for the starting job and Chris Johnson returns to the form that made him a fantasy monster.
The bad: What they should be concerned about: The defense is young, with seven projected starters having three years of experience or less.
Last playoff appearance: 2010 (lost in wild card round)
Longest playoff drought: 9 seasons (1978-86)
Other notable droughts: Even during the Peyton Manning years, the Colts never led the NFL in net offense. They haven't done that since 1976.
The good: They'll double or triple their win total (two) of 2011 if: New coach Chuck Pagano and rookie quarterback Andrew Luck instill a sense of belief for a brand new team.
The bad: They'll stay in the basement if: The defense, which gave up 430 points and allowed 144 yards rushing per game, can't get any stops.
Last playoff appearance: 2007 (lost in divisional round)
Longest playoff drought: 5 seasons (2000-04)
Other notable droughts: The Jaguars have never had a Pro Bowl quarterback.
The good: Why they can get to .500: The defense, which finished sixth in the league last season, returns 10 of 11 starters.The bad: Why they'll bottom out: Quarterback Blaine Gabbert looked shaky as a rookie last season and a fan base that's seen its team miss the playoffs in 10 of the past 12 seasons will be quick to turn on him and the team.
