With training camps ready to kick off around the NFL, intrigue surrounds a handful of starting quarterbacks. Here’s a closer look at three rather polarizing signal callers.

Cam Newton
Even if the Panthers match their 2012 season and amass another 7-9 record, Newton will head into 2014 as Carolina’s starting quarterback. Nobody will fault Newton if he can’t out-duel Matt Ryan and Drew Brees within the NFC South, especially when you consider the weapons that the Falcons and Saints have offensively. That said, more will still be expected of Newton as he heads into his third season. In seven of his final eight games, he averaged 245.6 passing yards per contest and threw 13 touchdowns compared to just three interceptions. He also rushed for 360 yards and four scores during that same span and continues to be one of the best playmaking quarterbacks in the NFL. But his accuracy was erratic in his second season and his decision making in the clutch also came under scrutiny. He improved when the Panthers took more off his shoulders and spread the wealth offensively, so look for new coordinator Mike Shula to build off of what Rob Chudzinski was able to accomplish with Newton in the second half of last year. Can Newton improve upon his career completion percentage of 58.9? Will the departure of Chudzinksi stall his progress? Will he prosper or fold in the fourth quarter of close games? Newton will once again be one of the more intriguing signal callers heading into the 2013 season.

Sam Bradford
Given the lack of playmakers, the carousel of offensive coordinators, and the suspect pass protection, there have been plenty of excuses for why Bradford hasn’t improved upon his rookie of the year campaign in 2010. But considering the offseason the Rams just had, there are no more excuses: Bradford needs to excel in 2013. Thanks to the free agent signings of Jake Long and Jared Cook, as well as the selections of Tavon Austin, Stedman Bailey and Zac Stacy, Bradford will be surrounded by more playmakers this season than at any point during his four-year career. The offensive line has also improved significantly over the past two offseasons (at least on paper), and this will be the first time that Bradford will play under the same offensive coordinator (Brian Schottenheimer) in back-to-back years. Will Bradford elevate his game is the question. According to Rotoworld.com, he’s completed just 46.4 percent of his red zone passes for 541 yards, 29 touchdowns and eight interceptions over the course of his career. And while the St. Louis Post-Dispatch points out that Bradford’s touchdown-to-interception ratio jumped to 9:1 in the red zone during the second half of the 2012 season, that came against San Francisco (twice), NY Jets, Minnesota, Buffalo and Tampa Bay, which all ranked 22nd or lower in red zone defense. Simply put, he needs to be more consistent on third downs and inside the 20 if this new-look Rams offense is going to fire on all cylinders. He’s wanted more responsibility at the line of scrimmage and he’ll get that under Schottenheimer, who wants Bradford to run more up-tempo looks Time will tell if Bradford can push to become an elite quarterback or settle for being a glorified game manager that doesn’t show the ability to elevate those around him.

Josh Freeman
Who is the real Josh Freeman? The quarterback that threw 16 touchdown passes to just three interceptions between Weeks 6 and 11 last season, or the one that finished with a TD:INT ratio of 6:10 during the Bucs’ 1-5 slide at the end of 2012? Freeman’s biggest issue heading into 2013 is overcoming pressure. He struggles when defenses rush him off the edge, he struggles when they put pressure in his face, and he struggles in a muddied pocket. Granted, most quarterbacks have issues when they’re under duress. According to Pro Football Focus, nine of Freeman’s 17 interceptions last year came when he was under pressure, which probably isn’t an uncommon percentage among starting NFL quarterbacks. But in his four seasons, the Bucs are just 24-32 with him as a starter, and no playoff appearances. Over that same span, Tampa Bay is also just 5-10 against Atlanta and New Orleans, and if Freeman can’t beat those two opponents than the Bucs will continue to fall short in the NFC South. Now, are those failures all on Freeman? Of course not. In fact, he was nearly unbeatable at one point last year, albeit with the aid of Doug Martin and Vincent Jackson. But it’s telling that the Bucs are willing to head into 2013 without extending Freeman’s contract. Greg Schiano wants and demands more from his quarterback, who has enough playmakers around him to succeed. (Tampa has done a nice job of collecting talent on both sides of the ball the past two offseasons.) If Freeman can’t become a more consistent playmaker, the Bucs may chalk up that 10-win season in 2010 as a fluke and look to move on next offseason.
