Eric Decker is the second best White outside receiver of the past 30 years, which is where he played much of his career, behind only Jordy Nelson. He had three thousand yard seasons, including one with the lowly Jets after the hive mind narrative was that he only did well in Denver because of Peyton Manning. His peak season was 2013 with a superb 87/1,288/11, and he also reached double digits in TD receptions in 2012 (13) and 2015 (12).
Reading his retirement statement, his passion seems to have waned. He made lots of money and has a celebrity wife. Pro athletes who are driven still play as long as they can, but with the money they make now, many can retire young and be set for life and pursue whatever interests they want. I wonder too what effect being unwanted last year as a free agent had on Decker, as no teams showed any interest in him despite how well he played with the Jets, until the Titans finally signed him cheap and then underused him with a lousy quarterback. Then being unwanted again this year, maybe he didn't stay in top shape physically and mentally and was already preparing for retirement and just didn't have it anymore when the Patriots signed him.
