Pete Prisco compiled a list of likely breakout players, including players like Teiler Eifert, Blake Bortles, Chance Warmack and Tyrann Mathieu. Missing from the list: any and all Tampa Bay Buccaneers. Which is a little odd, given Prisco's definition: players who haven't been to a Pro Bowl, but could get there this year. Mike Evans qualifies for that list, a does Lavonte David -- though another successful year for either player would not really be a breakout, just a continuation of their performance.
One player who I'd qualify as a breakout candidate, and really the only one I'd qualify like that on the Bucs roster, is tight end Austin Seferian-Jenkins.
