Arizona Cardinals quarterback Carson Palmer, at 36, is like a fine red wine. He was the best regular-season QB in the league in 2015, and that season was an exclamation point on a career filled with many more downs than ups. Drafted by the Cincinnati Bengals in 2003 (prior to Palmer's arrival, Cincinnati hadn't enjoyed a winning season since 1990), he suffered numerous injuries and poisonous front-office politics before he requested a trade in 2010. Out of spite, Bengals owner Mike Brown refused to honor the request, effectively sentencing Palmer to football purgatory after the team drafted quarterback Andy Dalton. Brown eventually relented and traded Palmer to the one franchise worse than hell — the Oakland Raiders. He spent two years playing awful Bay Area football before arriving via trade in Arizona. The following seasons have seen Palmer blossom into an elite quarterback. They say success is the best revenge after a toxic breakup, and last year was the gaudy diamond ring on Palmer's joyous middle finger to his old bosses.
