Here are the positions that need improvement for the Jaguars to be successful.
Clearly with five losses of one score or less a season ago, the Jaguars weren't that far away from being a respectable team. Quarterback play was a major problem as Blaine Gabbert simply wasn't very good and he seemed to regress as the season progressed. With an offseason of training plus a significant upgrade in talent on the outside, Gabbert should improve in 2012. If not, there will be considerable pressure to play veteran backup Chad Henne.
2. Right Tackle
The Jaguars had a major hole at right tackle last season as Guy Whimper manned the position for much of the season. Former second-round pick Eben Britton is likely playing for his future in Jacksonville as he's been underwhelming in the rare time that he's been healthy over his first three seasons. As important as the quarterback position is for the Jags, no signal caller is going to have legitimate success with a major hole at right tackle.
3. Wide Receiver
The Jaguars wideouts were the worst in the NFL last season. Mike Thomas was masquerading in the role of a "number one," when he's clearly an average slot receiver and the others will be fortunate if they ever start another game in the NFL. Laurent Robinson was brought in to give Blaine Gabbert a legitimate target and the Jaguars traded up in the draft to acquire Justin Blackmon. If these new acquisitions can get open consistently, the Jaguars will be able to move the chains and climb into respectability on offense.
4. Defensive End
It appears as if the Jaguars stumbled upon a star last season in Jeremy Mincey, but to take their defense from very good to great, Mincey must have a favorable bookend. Veteran Aaron Kampman will be given one more shot to resurrect his career after a pair of ACL injuries. If he can't go then the onus will be on rookie second-round pick Andre Branch to provide a rush.
5. Left Guard
Although Maurice Jones-Drew was the league's leading rusher last season, the Jaguars interior line, specifically left guard had a major hole. Rookie Will Rackley seemed overwhelmed for much of the season and he must play better in his sophomore campaign if Blaine Gabbert or Chad Henne are going to have enough time to throw.
