The Facts: Appearing on The Rich Eisen Show last week, HC Bruce Arians revealed Palmer entered last season with fatigue in his throwing arm after overworking in the months leading up to September. "He's one of the hardest working dudes I've ever been around, so we have to pull the reins back on him," Arians explained. "Last year, he came in to September, he had already wore his arm out by overthrowing all summer. We found a nice regimen, [and by] November and December he was playing as good as he's ever played."

Diehards Line: The Cardinals' disappointing showing in 2016 was a tale of two seasons for Palmer. By midseason, Arians felt compelled to defend his quarterback. Palmer was struggling behind an injury-ravaged offensive line while wideouts Michael Floyd and John Brown disappeared for long stretches. From Thanksgiving through the end of the season, though, Palmer had recaptured the form that had propelled him into the 2015 MVP race. And now we know why. Palmer acknowledged in May a new regimen was needed to adapt to his NFL twilight years. The regimen referenced by Arians included sitting out Wednesday practices down the stretch and curtailing Palmer's throwing in March and April. By the time the Cardinals were wrapping up their offseason program in June, Arians was delighted to find Palmer's arm was "stronger than ever."
