TAMPA, Fla. -- Each Sunday this season has become a lesson for Tampa Bay Buccaneers quarterback Jameis Winston. Last Sunday, there weren't many positives to find in a four-interception performance against the Carolina Panthers.

So this early in the rookie's NFL career, Winston knows he remains a work in progress.

"I'm learning about myself," he said Wednesday. "I'm adjusting to this game. I'm trying to get better at something every week. ... Every week, I'm trying to work on something and improve on something. For the rest of the season and from now on, I have to work on not turning the ball over."

He turned the ball over plenty in the loss against Carolina. In addition to the four interceptions, Winston also failed to collect a snap from center Joe Hawley on the game's second offensive play.

Winston's mishaps led to 27 points for the Panthers. "Not good enough," Bucs offensive coordinator Dirk Koetter said. "We're going to have some growing pains, and we certainly had some last week."

Winston has produced mixed results in the Bucs' 1-3 start. He has completed 73 of 133 passes for 965 yards with six touchdowns and seven interceptions. He showed progress with his decision-making in Week 2 against the New Orleans Saints and Week 3 against the Houston Texans, when he had just one combined interception. But his play against Carolina and the two interceptions in Week 1 against the Tennessee Titans reveal how much work remains.

"You have to get your hand burned in the fire, and then you start seeing," Bucs coach Lovie Smith said. "For us, it's about the turnover ratio each week as you look in the league.

"I think you learn from every situation you're in -- tough situation, great things that happen to you. And that's what he has gone through. In a month, four games in a football season, the different, tough emotions that you go through during the football season, he has been through that. He has learned. We saw him come back from a tough performance early on and bounce back that next week. And that's what we're going to see. He's already past that."

Winston should face a favorable matchup Sunday against the Jacksonville Jaguars, who rank 26th in the NFL in passing defense by allowing 278.5 yards per game. He's eager for the chance to recover.

"It's a good thing, because you can only go up," Winston said of rebounding from last Sunday. "So definitely, I try to motivate myself to get back in the game and go play, because that's what I'm here to do. I'm here to play."
