Marshawn Lynch’s obsession with Skittles is well-documented. Well, at least we thought so — ESPN has now taken it to a new level by examining his candy craving on “Sport Science” .

As you likely know, the Seahawks running back has a habit of eating a bag of Skittles on the sideline during football games. His tradition began in high school, when his mother would give him a bag of Skittles before every game, and it lives on to this day.

In fact, it’s become a running gag on the sidelines. And, after the nation noticed Lynch’s little habit during a “Thursday Night Football” game last season, it’s become something more — the company that makes Skittles, Mars Inc., reportedly sent Lynch two years’ worth of candy and a custom dispenser.

The Seattle star later got fined by the NFL for wearing Skittles shoes during the Seahawks’ game against the 49ers a year ago.

But for all this time, there’s been one unanswered question: Do Skittles make Marshawn Lynch better?

Until now. That’s what ESPN examined, checking Lynch’s blood-sugar levels before and after consuming a half-ton of Skittles (OK, maybe not that many) and measuring the effect on his speed, reaction time and grip strength. And the results may surprise you.

Once again, Marshawn Lynch makes an obligatory appearance on the team's injury report. His owners should have no worries, though, as he's surpassed the 100-yard mark in back-to-back blowout wins on just 21 total carries. Friday's injury report should impart his must-start status for Week 16.

Marshawn Lynch needed only a season-low 10 carries to generate 113 rushing yards and a touchdown on Sunday against the Bills, his eighth 100-yard effort in 14 games for the Seahawks this season.
