The Facts: At its highest level, football requires perseverance. With that in mind, it's fair to wonder if Palmer will overcome the setback of a ghastly six-turnover performance in the Cardinals' NFC Championship Game loss. Will Palmer's postseason failures continue to haunt him? Or will the 36-year-old quarterback bounce back as the leader of a stacked Arizona roster? HC Bruce Arians is confident it's the latter. "There's no doubt in my mind," Arians said this week. "He'll come back with more vengeance than before the injury."

Diehards Line: Arians' comments echoed those of GM Steve Keim and as NFL.com suggests, it's easy to understand why Arians has the utmost faith in his quarterback. When Palmer first shredded his knee in 2006, doctors deemed the injury a "four" on a "scale of one to three." When the Cardinals traded a late-round pick for Palmer in April of 2013, he was viewed as a washed-up journeyman coming off a lingering elbow injury that sapped his arm strength. Just as Palmer started hitting his stride in Arians' offense, he suffered nerve damage in his throwing shoulder. Three months later, he tore the ACL in his left knee for a second time. Faced with a mountain of adversity, Palmer trained like maniac to return stronger than ever, leading the Cardinals franchise to its best regular season in nearly 70 years.
