After nine years in the NFL, announced his retirement.

Jones-Drew had plenty of ups -- and plenty of downs, unfortunately -- in his career, but just how good was he when he had those ups?

Well, in 2011, Jones-Drew won the rushing title after compiling 1,606 yards on 343 attempts (a 4.68 yards per carry average). A running back had maintained a 4.6-plus yards per carry average on 340 or more attempts just 23 times in NFL history, including MJD's 2011 season.

However, after amassing 49 rushing touchdowns (and 5 receiving touchdowns) in his first four seasons in the league from 2006 to 2009, Jones-Drew was able to reach the end zone just 25 times total in his next five seasons, four of which came with the Jacksonville Jaguars.

In 2014, his final year in the league, Jones-Drew went to Oakland but saw just 43 carries in an injury-shortened season.

MJD certainly had his share of NFL glory, posting double-digit touchdowns in three of his first four seasons, but he also wound up playing on some of the worst offenses in recent NFL history.

So what do our metrics have to say about his career?

The Early Days

Jones-Drew was a touchdown-scoring phenom in his first four seasons -- we've already established that. But in his first three seasons (during which he scored 13, 9, and 12 touchdowns, respectively), he carried the ball just 166, 167, and 197 times.

In 2009, he racked up 15 scores on 312 carries.
