Gregg Rosenthal will project post-draft starting lineups for all 32 teams -- because that's his idea of fun.
» Houston's offensive line was among the league's worst last year. Unless third-round pick Martinas Rankin surprises as a blind-side protector, the tackle situation doesn't look much better this time around. The Texans threw money at their guard problem, with two starters possibly found in free agency. After former Chiefs guard Jeff Allen struggled to live up to his contract last year, the team gave another former Chiefs guard (Zach Fulton) good money.
» Add it all up, and there are few AFC teams with greater boom-or-bust potential than Houston. Anything between 11-5 and 5-11 feels on the table, depending on health and Watson's development.
» Andrew Luck's early offenses were loaded with receivers and not much help from the offensive line. That formula could be flipped if general manager Chris Ballard's emphasis on toughness up front pans out.
» This is the most promising O-line the Colts have fielded in a while. It shows progress that Jack Mewhort, a quality starter plagued by injuries, and veteran Matt Slauson aren't listed among the starters. If rookie guards Quenton Nelson and Braden Smith live up to their draft pedigree, right tackle might be the only relative weak spot.
» Ryan Grant is the favorite for the No. 2 wide receiver job, based on the money he received in free agency. An injury to Hilton would be devastating; this wideout crew is thin, with Chester Rogers as the No. 3 option and very little behind him. Eric Ebron, signed as a catch-first tight end, might wind up as the team's de facto third receiver. This is a far cry from the group of receivers who reached the 2014 AFC title game with Luck.
» The holes on offense are more concerning because Luck's side of the ball has to carry the team. There isn't a position group on the Colts' defense that is more talented than the NFL average -- except perhaps safety, where Matthias Farley comes off the bench. The team is transitioning to a 4-3 base defense and many of the old pieces -- like John Simon -- don't quite fit. Free-agent pickup Denico Autry can play inside or out, depending on the down.
» The Jaguars brought back nearly the entire defense that destroyed the league a year ago. Pulling off an encore will be difficult, but the defensive line shouldn't slip much with a full season from Marcell Dareus. First-round pick Taven Bryan will come off the bench and former No. 3 overall pick Dante Fowler remains a sub.
» One of the only changes on defense will come from Myles Jack moving to middle linebacker on every down. The team also downgraded at slot cornerback after losing Aaron Colvin. The lack of cornerback depth makes keeping A.J. Bouye and Jalen Ramsey healthy a key. Jacksonville was one of the healthiest teams in football last season and had a favorable schedule -- two factors that aren't likely to repeat.
» The Jags have done everything possible to make Blake Bortles feel more comfortable. They gave him a new contract, no competition and a stronger offensive line. Even after losing Allen Robinson, the depth at receiver is strong. Keelan Cole played well last year, but Dede Westbrook's upside is higher. Second-round pick D.J. Chark will also be a threat, especially if free-agent pickup Donte Moncrief doesn't pan out. There are five promising wideouts here, and tight end Austin Seferian-Jenkins might have been a steal in free agency.
» It speaks to the Jaguars' stability that their battle royale for receiver snaps is practically the only unsettled position on either side of the ball.
» Derrick Henry and Dion Lewis form a fun backfield, but there are still question marks about Marcus Mariota's weapons. Corey Davis flashed potential as a rookie, but it's asking too much for him to be a No. 1 receiver already. Taywan Taylor didn't graduate past gadget player as a rookie, with only 16 catches. Tajae Sharpe, a pleasant surprise in 2016, returns from injury in what's an otherwise thin group.
» The entire offensive line returns after a season where it didn't quite play to its reputation. A return to the unit's 2016 form could make the Titans true AFC title contenders.
» General manager Jon Robinson has done an excellent job remaking this roster. Robinson arrived with virtually nothing to work with in the secondary, and now the group looks like an asset. Adoree' Jackson has breakout potential in his second season.
» While this is coach Mike Vrabel's first year at the helm, it is Year 4 for Mariota and Year 3 for Robinson. It's go time for an organization that has done a nice job crawling out of a two-year hole in 2014-15, when the Titans only won five games combined.
