Houston Texans: 20/1
I don't like any of the lesser options, as there's no real value with anything worse than 20/1. The Texans are worth a look, however, as they'll have Deshaun Watson, J.J. Watt and Whitney Mercilus back from injury. Watson will also have experience, which will be huge. Barring a similar amount of injuries, Houston will be considered the favorite to win the AFC South, and they could obtain a first-round bye. I think there's a good chance the Texans are 8/1 or 10/1 by next December.
Carolina Panthers: 20/1
The Panthers certainly have some flaws, but despite those, as well as injuries to Cam Newton and Luke Kuechly, they still finished 11-5 in 2017. They can fill some needs this offseason and become the favorite to win the NFC South.
Oakland Raiders: 30/1
Of the 30/1 teams, I like the Raiders the most. I can't trust the Chargers, while the Chiefs may move forward with Patrick Mahomes, who has tons of upside, but lacks experience. The Raiders, meanwhile, were one of the favorites heading into 2017, so 30/1 seems like a great bargain. Jon Gruden and Greg Olson will get the most out of Derek Carr, who should have a big rebound year in 2018.
Denver Broncos: 40/1
I would bet the Broncos right now. If they land a solid quarterback, this number will plummet to 20/1, or even 15/1. Denver has a great roster, but lacks a signal-caller and a couple of other things. If the Broncos can obtain, say, Kirk Cousins, they'll likely win at least 10 games, if not several more.
Arizona Cardinals: 40/1
I can copy what I wrote about the Broncos and paste it here because Arizona is in the same situation. Carson Palmer has announced his retirement, so the Cardinals will be looking for a new quarterback. If they land a talented one like Kirk Cousins, this number will fall to 15/1 or something like that.
Chicago Bears: 100/1
Of all the super long shots, I like the Bears the most. They pulled upsets over the Steelers, Ravens and Panthers in 2017 despite having a quarterback with no experience. Mitchell Trubisky will have another year of experience under his belt next season, and new head coach Matt Nagy should help his young signal-caller take the next step in his development.
