NFL training camps are open, and for millions of people worldwide their fantasy football preparation has begun in earnest. Here at Sports World News we will break down all 32 NFL teams in terms of their fantasy value. Readers will find the must-own players in every format, the sleepers in specific formats, and hidden gems only necessary for those in very deep leagues.

Today's preview will be on the Tampa Bay Buccaneers. As always, average draft position (ADP) is pulled from FantasyPros.com.

7 Players who might lose their job in 2015

Must Owns

Mike Evans, WR, (ADP: 27): Evans put up more than 1,000 yards receiving and 12 touchdowns last season as a rookie—and he did it with a combination of Josh McCown and Mike Glennon throwing the passes. Evans is the 12 WR off the board right now, but even though Jameis Winston is no guarantee to be great, he’s easily an upgrade over what Evans had in 2014.

Vincent Jackson, WR, (ADP: 75): Jackson is pretty much a lock for 1,000 yards and 70 grabs, but last year his TD total dipped to two. Part of that is a younger, better receiver entering the fold, but part of that is also a combination of shoddy QB play and bad luck. V-Jax will provide value at No. 75.

Beware these 3 possible busts at RB

Doug Martin, RB, (ADP: 100): Muscle Hamster has been dreadful for two seasons, and somehow enters 2015 fantasy relevant because of his role. Despite averaging fewer than four yards per carry, scoring three total touchdowns, and playing in just 17 of a possible 32 games, Martin matters. No. 100 overall might still be overdrafting Martin, especially with a lot of competition in the backfield, but for now he’s the dude.

Sleepers (Best Format)

Jameis Winston, QB, Standard (ADP: 139): Winston shouldn’t be drafted as anything more than a QB2 in two-QB leagues, but with the weaponry available to him in the passing game there is Top 10 upside to him.

Charles Sims, RB, Standard (ADP: 127): Sims was believed to be entering 2015 as the starter, but someone on the Bucs’ staff must have noticed he averaged 2.8 yards per carry last year. Sims is a sleeper based on his opportunity to usurp the role from Martin, but he’ll be far from an elite option even as a three-down back for Tampa.

Austin Seferian-Jenkins, TE, Standard (ADP: 214): His 2014 numbers don’t indicate a big time season this year, but at No. 214 you are not taking much risk. He’s perfect as a late flier to back up your starter, but for the truly bold just snap him up and plug him in.

Deep Finds (Best Format)

Bobby Rainey, RB, PPR (ADP: 212): Rainey is underrated, plain and simple. If Martin fumbles, Lovie Smith may turn to Rainey instead of Sims thanks to his ability to catch passes.
