COACH: CHUCK PAGANO
Fourth season (33-15, .648)
LAST SEASON: 11-5, won division, lost to New England, 45-7, in AFC Championship
OUTLOOK: Andrew Luck has done most everything you could ask of a young quarterback -- except beat the Patriots. The Colts' fourth-year quarterback is a miserable 0-4 against Tom Brady's Patriots, including last year's blowout loss in the AFC Championship Game -- which is known more for allegedly deflated footballs than Luck's woeful performance. Luck's development has been otherwise remarkable. He is an MVP-caliber player who almost always gives his team a chance. Now if the defense can return the favor, maybe the Colts could be Super Bowl contenders.
COACH: BILL O'BRIEN
Second season (9-7, .563)
LAST SEASON: 9-7, second in division
OUTLOOK: Colorful coach O'Brien showed his feisty -- and often profane -- side during this summer's edition of "Hard Knocks", and by most measures, his team looks as if it will be improved. The key, of course, is whether Brian Hoyer can be a reliable passer who can match the Texans' defense, led by the brilliant J.J. Watt. The dominant DE might be the best player in the entire game, and he makes everyone around him better. One problem area: the injury-related absence of RB Arian Foster, who will miss a good chunk of the season following hernia surgery.
COACH: KEN WHISENHUNT
Second season (2-14, .125)
LAST SEASON: 2-14-0, fourth in division
OUTLOOK: Marcus Mariota provides hope for a team that bottomed out last year and earned the right to draft Oregon's Heisman Trophy quarterback. Mariota enjoyed a solid preseason, although the transition once the real games start might not go as smoothly. Even so, at least there is a major building block in place for the future. A pedestrian defense got a much-needed boost with the offseason signing of Washington LB Brian Orakpo, but there is still work to be done on that side of the ball. CB Jason McCourty continues to be a reliable presence in the secondary.
COACH: GUS BRADLEY
Third season (7-25, .219)
LAST SEASON: 3-13-0, third in division
OUTLOOK: The Jaguars put Blake Bortles into the lineup far earlier than planned last year; the idea was to bring him along slowly, but he showed too much promise in training camp not to get the nod. But he paid the price with a difficult rookie season, in which he was sacked a league-high 55 times. He seemed more comfortable this preseason, and had a better command of the offense. Jacksonville won't get any contributions from first-round pass rusher Dante Fowler, who is out until next year because of an ACL injury.
