Many teams made big splashes in the free-agency period, but others stood pat.
This will cost these teams in the future, and could lead to another disappointing season for them.
Here are five teams that failed to address key needs in free agency.
The Jets have had a disaster off an offseason so far.
After stumbling to an 8-8 record last season, the team entered the free-agency period with gaping holes at safety, outside linebacker, right tackle and wide receiver.
So far, the franchise has only addressed one of those needs, with the acquisition of LaRon Landry.
Landry is a talented player, but he is way too injury-plagued to rely on in a weak position.
The team spent unnecessary salary cap room with the signing of polarizing quarterback Tim Tebow, a player who is more likely to do more harm than good in the locker room.
Gang Green has turned into a circus, and will most likely be heading towards another disastrous season.
The Jets are not the only AFC East team that had an awful free-agency period.
The Dolphins failed to address the most important need on the roster—quarterback.
Miami lost the bidding sweepstakes for Peyton Manning and were spurned by both Matt Flynn and Alex Smith.
The franchise's biggest signing was 34-year-old David Garrard, who was out of the league last season.
It seems that no one wants to go to South Beach. The team will enter the 2012 season with longtime-backup Matt Moore as the starting quarterback.
The Dolphins have a talented team, but without a franchise quarterback, they will never succeed in a tough division.
The Texans are coming off the most successful season in franchise history, but they have had a disaster off an offseason so far.
The team lost three Pro-Bowl caliber players, superstar defensive end Mario Williams, linebacker DeMeco Ryans and right tackle Eric Winston.
The team is yet to replace any of these three stars accordingly.
Houston also has a dire need for a No. 2 wide receiver to start opposite Andre Johnson. The team has struggled to develop any sort of passing game without Johnson for years now.
The Texans have regressed significantly this offseason, and their place among the AFC elite could be threatened.
The Browns may be the ultimate losers of free agency.
The franchise once again struggled to attract any key free agents, as they lost out on Mario Williams, Peyton Manning and Matt Flynn.
Colt McCoy has done nothing to impress in his two years as starting quarterback, but the team failed to sign any solid signal-callers.
The team also lost one of its most valuable offensive weapons in Peyton Hillis. They now have no starting-caliber running backs on their roster.
Wide receiver is also a mess in Cleveland. The team does not boast a single dangerous receiving threat, and made no moves to acquire any elite wideouts in free agency.
In the NFL's toughest division, the Browns are bound to be the weakest link again in 2012.
The Rams made major moves with the coaching staff, made a terrific draft trade with the Redskins and brought in a Pro Bowl center in Scott Wells—but the team still missed out on filling several key needs.
The team went a dismal 2-14 last year, and has major questions on both sides of the ball.
St. Louis boasts one of the worst receiving corps in football, and still has a lack of talent on the offensive line, particularly left guard.
The Rams are also a mess on defense right now. They failed to fill key needs at outside linebacker and defensive tackle, and have questions in the secondary.
St. Louis is heading towards another subpar season, even in a weak division.
