Biggest Takeaways from Tampa Bay Buccaneers' Week 4 Loss

The Tampa Bay Buccaneers endured another embarrassing home loss on Sunday, falling to the Carolina Panthers 37-23 and dropping their record to 1-3 for the season.

The Bucs have yet to win a regular-season game at Raymond James Stadium under head coach Lovie Smith, who is just 3-17 overall since taking over for Greg Schiano after the 2013 season.

Silver linings were few and far between for the Bucs in Week 4, as turnovers and a struggling kicking game continue to cost them valuable points and opportunities to keep their defense fresh. A few players are still flashing talent, but the big picture of the Pewter Pirates is still stuffed with far too many mistakes.

What did we learn about the Bucs in Week 4?

Kicking Struggles Aren't Over Yet

After missing four of his six kicks in Week 3, Kyle Brindza missed three more in Sunday's loss to the Panthers, leading the Bucs to release the Notre Dame product on Monday, the team announced.

Brindza's misses—five field goals and a pair of extra points—cost the Bucs a potential 17 points over the past two weeks. His strong leg helped win him the job with a stellar performance in the team's final preseason game, but his back-to-back awful performances were simply too much for the team to stomach.

It's not clear whom the Bucs plan to bring in to replace Brindza at this point, but it wouldn't be a surprise if it's a veteran with plenty of experience and a track record of consistency from manageable distances.

Doug Martin's Resurgence Continues

After showing up to training camp 20 pounds lighter and fully healthy, Doug Martin looked ready to return to his rookie-year form, when he racked up nearly 2,000 total yards and made the Pro Bowl in 2012.

So far this season, his play has backed up that expectation, with his best game so far coming on Sunday. Against a Panthers defense ranked fourth in the league against the run—allowing just 75 yards per game—Martin carried the ball 20 times for 106 yards and a touchdown. He also added five catches for 37 yards, finishing second on the team in both categories.

After being hampered by multiple injuries over the past two seasons, Martin looks like his old self in 2015 despite playing behind an offensive line that is still trying to play with consistency. Especially with a rookie quarterback under center in Jameis Winston, the Bucs should lean on Martin as much as they can this year.

Jameis Winston Still Has a Long Way to Go

Growing pains should be expected from a rookie quarterback, but after taking good care of the ball over the past two games, Jameis Winston's five-turnover performance on Sunday was a harsh reminder of the NFL learning curve.

The 21-year-old's willingness to take chances in the passing game was well-known during his Florida State career, so fans shouldn't be too surprised at his high interception total so far this season. With six touchdown passes and seven interceptions—two for touchdowns—Winston is quickly finding out how unforgiving pro secondaries can be when rookie mistakes are made.

There have been flashes of his limitless potential, and there should continue to be. But Winston will have to make better decisions moving forward if he wants to develop quickly and stave off the grumbling of the fanbase.

Vincent Jackson Still Playing Like a No. 1 Receiver

After Mike Evans burst onto the scene with a record-breaking rookie campaign in 2014, it appeared as though Vincent Jackson would be transitioning into the next stage of his career as nothing more than a complement to the young playmaker.

But so far this year, Jackson has proved he's still got plenty left in the tank, with Sunday's effort against Carolina as his best evidence yet. Jackson posted season highs with 10 catches for 147 yards in Week 4, hauling in his second touchdown of the season.

A hamstring injury kept Evans from registering a reception in Tampa Bay's first two games, and though he hauled in seven passes for 101 yards in Week 3, he had multiple drops and only caught three passes on Sunday against the Panthers.

As Evans tries to fight off a potential sophomore slump, it looks like Jackson is more than capable of handling plenty of targets, proving he can still stretch the field, move the chains and find the end zone.

Missed Opportunities Continue to Sting

It's easy to expect a loss when a team turns the ball over five times, but the Bucs had plenty of opportunities on Sunday to turn the tables with their own big plays and failed to do so.

Whether it was a forced fumble by safety Chris Conte that took an unlucky bounce, a dropped interception in the end zone by linebacker Lavonte David or the offense failing to turn a key turnover deep in enemy territory into points, the Bucs couldn't capitalize on their chances in Week 4.

If they want any hope of being competitive the rest of the way in 2015, they'll have to take advantage of gift-wrapped moments they could use to swing momentum in their favor. If the Bucs can't and they continue to send gifts the other way, it'll be another long season for Tampa Bay fans.
