According to the tried and true saying, there are only two certainties in life: death and taxes.

But with news of Panthers' running back suffering a hamstring injury during the first week of training camp, I’d like to make an addition to the saying.

Death, taxes, and Jonathan Stewart on the injury report.

Stewart’s injury comes as no real surprise to those who have followed his career, and should place serious doubt on his viability moving forward. And although he claims he will be ready for Week 1, frequent soft-tissue injuries have proven to a major red flag.

Prior to his injury last week, In a crowded Panthers backfield devoid of any real standout talent, Stewart was as good as bet as anyone to get the majority of the carries this season.

While Stewart attempts to get healthy, it appears the door is wide open for another running back to take control of the backfield during training camp.

Will DeAngelo Williams Be Relevant Again?

The most tenured Panthers' running back is also the most likely to win the starting job outright if Stewart can't get right by Week 1.

Aside from 2010 when he missed 10 games, According to Fantasy Football Calculator, Williams is currently the RB44 in 12-team, PPR drafts. While a 10th-round pick can usually be thrown away without any real loss of equity, players with much greater upside such as Jeremy Hill and Carlos Hyde are being selected near Williams. To be fair, however, our projections do like Williams much more than drafters do.

Williams has proven to be a useful, efficient running back when given the chance, and with Stewart shelved yet again, he could take the starting job and run with it. But his lack of opportunity for touchdowns due to both Newton and Tolbert make him a less appealing option for fantasy purposes.
