, 37, is entering his 15th NFL season and . So it should come as no surprise to hear that the Arizona Cardinals quarterback won't guarantee his return for a 16th season.On Tuesday, Palmer revealed that he'll once again weigh retirement after the season." Drew Smyly Jersey I love every facet of it," Palmer said, "I don't want to stop. But I'll have to wait and make that decision after the season."So no, he won't answer the retirement question yet."That's a great question," Palmer said, "and I don't have an answer."Palmer's quality of play will likely play a role in his decision. In 2015, Palmer performed like an MVP- Chicago Cubs Jersey caliber quarterback, completing 63.7 percent of his pa ses, averaging 8.7 yards per attempt, and throwing 35 touchdowns against 11 interceptions. As a result, the went 13-3 and nearly journeyed all the way to the Super Bowl. After the season, retirement talk was nonexistent. But Palmer regre sed in 2016. His completion percentage sank to 61.0, he averaged 7.1 yards per attempt, and he threw 26 touchdowns against 14 interceptions. As a result, the Cardinals went 7-8-1 and mi sed the playoffs. Retirement Robel Garcia Jersey talk lasted until he announced his intention to return.Other factors behind the Cardinals' struggles were at play, of course, like Palmer's pa s protection (he was sacked 40 times in 2016 compared to just 25 in 2015) and special teams woes. Regardle s, it's probably time for the Cardinals to begin planning for life after Palmer, because even if his retirement doesn't occur next offseason, it's coming soon.Once he retires, he seems unlikely to head into coaching in the NFL "The hours I watch our coaches put in, I don't want to work that hard in retirement," Palmer said John Lackey Jersey . "I want to have a life."They'll likely be forced to find his succe sor in the draft. They pa sed on taking a developmental prospect like or in this year's draft, so they'll likely enter the season with and behind Palmer on the depth chart. Luckily, next year's quarterback cla s is supposedly one of the best in recent years.Other long-term concerns also exist in Arizona, namely at receiver. The team not only lost last year after his arrest, but it's also dealing with the po sibility of losing Jason Heyward Jersey when Palmer walks away. Like Palmer, Fitzgerald also weighed retirement this offseason before . The Cardinals won't have their quarterback and receiver for much longer. Point being, the Cardinals need to take advantage by cashing in with a title while they still can.
