The problems that plague Andrew Luck are the same that hinder Carson Palmer and pretty much any other quarterback or team that was expected to light it up this year but hasnt.As much as an ailing receiver, hurting running back or bad play calling, a patchwork offensive line can carve into a teams efficiency, confidence and, ultimately, its win total.Indianapolis and Arizona were among the teams expected to reach the playoffs this season, but are now dealing with losing records in large part because of uncertainty in their offensive lines. They have given up the second and third-most sacks this season, respectively. Minnesota (11), Carolina (11) and Miami (12) lead the league in number of linemen used this season; only the Dolphins are playing well heading into December.Looking back to last year, I think we got through most of the year with the same guys, said Palmer, whose current line includes two players who werent starters when the season began and a third lineman playing out of position. This year, its been the exact opposite. Its been different guys, different spots, different weeks.Each team has 53 roster spots, and once coaches and GMs move beyond their main playmakers, they look for multi-faceted players who can back up in some positions and play special teams. Because offensive linemen arent common on special teams, the number of spots available for them are often limited -- usually seven or eight on a roster.Injuries are inevitable. That leads to juggling, shifting positions and adding new players. How well the new pieces fit into whats designed as a finely tuned machine, with centers shouting out play calls to the line much the way the quarterback does to the entire offense, can dictate whether injuries equal big trouble or a minor setback.It seems like its a broken record every year, said Colts coach Chuck Pagano, whose team has allowed 38 sacks so far -- one more than all of last season -- en route to a 5-6 mark. Luckily we have a bunch of guys that have some position flexibility and can play multiple spots, but it affects you.Aware of the beating their quarterback was enduring, the Colts used their first-round draft pick this year on a center, Ryan Kelly. He started the first 11 games, but injuries piled up around him. The Colts have used six different line combinations and one player, rookie Joe Haeg, has started at three different spots.It works the other way, too.The Titans started seven different tackles in 2014, en route to a 2-14 record, all of which put them in position to draft Marcus Mariota in 2015.But it was moves the Titans made last offseason that helped put Mariota in the position hes in today -- a half-game out of first place with the leagues third-best rushing attack and just 18 sacks allowed after giving up a league-high 54 last year.Tennessee signed free agent center Ben Jones, used the No. 8 pick on tackle Jack Conklin and traded receiver Dorial Green-Beckham to Philadelphia for tackle Dennis Kelly. None of these moves made headlines the way Mariotas selection did in 2015.But the Titans depth on the offensive line has made a difference.Getting (Kelly) with that trade was as big a trade as we had this year, coach Mike Mularkey said.Heading into Sundays game against Miami, Ravens coach John Harbaugh was asked about the Dolphins shuffled offensive line -- three starters have missed all or part of the last two games -- and immediately reflected on his own teams problems.We were ... cobbling together an offensive line and guys were playing out of position. Its very challenging, Harbaugh said. The really great offensive line coaches prepare for that.The Ravens started the same offensive line for the first three games of the season and went 3-0. Injuries set in, and Baltimore lost four straight -- part of a stretch of eight straight games in which they started a different line combination. They head into Sundays game having won three of four, as the idea of not knowing who theyre going to line up next to has become less jarring.Its definitely easier to have someone youve been playing with because you build chemistry over a period of time, said Ronnie Stanley, the Ravens first-round pick this season, who missed four games earlier this season with a foot injury.And yet, sometimes chemistry isnt all its cracked up to be. The Bengals have started the same offensive line all 11 weeks this season. But Cincinnati has given up 32 sacks -- fourth most in the league -- and is on pace for its worst rushing attack since 2010. Last week against Baltimore, four of Andy Daltons final eight passes were batted down at the line and Cincinnati fell to 3-7-1.---AP Sports Writers Michael Marot in Indianapolis, Steven Wine in Miami, Teresa Walker in Nashville, Bob Baum in Phoenix, Joe Kay in Cincinnati and David Ginsburg in Baltimore contributed to this report.

CHAPEL HILL, N.C. -- North Carolina keeps sharing the ball and putting up big numbers, proving the fifth-ranked Tar Heels still have plenty of offensive punch despite losing a lot of production from last year.Hall of Fame coach Roy Williams is more focused on getting more consistency from his team on the defensive end, and maybe a little more attention to detail, too.Joel Berry II scored 23 points and UNC shot 53 percent to beat Long Beach State 93-67 on Tuesday night for a third straight lopsided win to open the season.Kennedy Meeks added 15 points for the Tar Heels (3-0), who scored the games first 14 points and led by 23 points by halftime. That dominating start was enough to erase any doubt about the outcome, though Williams was aggravated enough at one sloppy second-half stretch that he angrily punched a clipboard to the court during a timeout.That first 10 minutes of the second half ... that was about as bad offensively as Ive seen us in 31 practices and three games and one exhibition, Williams said, adding he also wants more from his team defensively.Still, that stretch was little more than a blip, the kind of moment that will give Williams something to focus on in coming practices. The Tar Heels -- who shot 59 percent in the opening half -- never let the 49ers closer than 16 after halftime.Gabe Levin scored 17 points for Long Beach State (1-2), who never recovered from an awful start that included making 8 of 31 shots (26 percent) in the first half. The 49ers finished at 36 percent and missed 20 of 26 3-pointers.Im disappointed that we didnt take advantage of the opportunity to come out here and play a little better early, Long Beach State coach Dan Monson said.BIG PICTURELong Beach State: This game came roughly 48 hours after a loss at Wichita State as part of a demanding opening stretch that includes a stop at No. 12 Louisville on Thursday as well as visits to UCLA, Washingtoon and Kansas before the end of November.ddddddddddddSo far, at least, Long Beach State is struggling to keep up, losing the past two games by a combined 63 points.This game will help us get better, Monson said. Hopefully Thursday will too.UNC: Williams angst aside, the Tar Heels offense has gotten off to a quick start. They had 20 assists on 32 baskets after assisting on 72 percent of their made shots through the first two games. They have also scored at least 93 points in all three games -- so far, so good for an offense with new people inheriting key roles from last years NCAA finalist.POLL IMPLICATIONSUNCs three wins have come by an average of nearly 29 points per game, part of the reason the Tar Heels climbed one spot in this weeks AP Top 25 poll.BERRYS STARTBerry is off to a fast start in his development as UNCs No. 1 threat.
