2015 Tampa Bay Buccaneers training camp preview

The Tampa Bay Buccaneers open training camp on Aug. 1 at One Buccaneer Place in Tampa, Florida. Here’s a closer look at the Buccaneers' camp, which wraps up on Aug. 19:

Top storyline: For a change, the Bucs have one of the top storylines in the league. That’s the development of rookie quarterback Jameis Winston. The No. 1 overall draft pick is sure to be the focus of tons of local and national attention. Winston’s off-field issues were discussed at length during the draft process. Now it’s time to see what he can do on the field. He got off to a good start in the offseason program. He impressed the coaching staff with his work ethic, frequently being the last player to leave the facility at night. He did a good job of picking up the playbook and developing chemistry with wide receivers Mike Evans and Vincent Jackson. But the Bucs didn’t rush Winston, having him share first-team snaps with Mike Glennon throughout the offseason. But now it's time for Winston to start getting all of the first-team snaps to get him ready to start on opening day.

Position battles to watch: Keep a close eye on the running backs. The coaching staff likes to say that Doug Martin still is the starter. But hopes are very high for second-year pro Charles Sims. A strong preseason by Sims could shake up the depth chart. ... The Bucs are in a win-win situation at defensive tackle opposite Gerald McCoy. Clinton McDonald and Henry Melton will compete for that starting role with the loser still getting a lot of playing time as a rotational player. ... The two starting safety jobs are wide open, with veterans Bradley McDougald, D.J. Swearinger, Chris Conte and Major Wright competing for the jobs.

Veterans to watch: Jackson is 32, an age when many receivers start slowing down. Jackson showed no signs of decline last year when he had a 1,000-yard receiving season despite some shaky quarterback play. But he could be even better this year with the arrival of Winston. Plus, Evans is bound to take some defensive attention away from Jackson. ... Cornerback Mike Jenkins missed last season with a pectoral injury. Johnthan Banks blossomed in his absence, but Jenkins still could win the starting job back with a strong preseason.

Rookies to watch: Winston isn’t the only rookie who will be under heavy scrutiny. The Bucs used a pair of second-round draft picks on offensive linemen Donovan Smith and Ali Marpet as they tried to overhaul an offensive line that was dismal last season. The team wants to start Smith at left tackle and Marpet at right guard. But Smith will have to beat out second-year pro Kevin Pamphile and Marpet will have to beat out Kadeem Edwards.

Bubble watch: Receiver Robert Herron didn’t have a good rookie season last year. He still has rare speed, but his spot on the roster is shaky. That’s because the Bucs used draft picks this year on Kenny Bell and Kaelin Clay. In addition to playing receiver, Bell and Clay have the ability to factor in the return game.

Starting over: After he was acquired in a preseason trade from New England last year, guard Logan Mankins didn’t seem happy and his play wasn’t great. But Mankins, a former Pro Bowler, showed up for the offseason program with a new attitude and expressed his desire to be a leader on the offensive line.
