Compared to his production, Pro Bowl running back DeMarco Murray is expected to get a modest contract offer from the Dallas Cowboys. Murray led the NFL with 1,845 rushing yards and 13 touchdowns last season, but it's unlikely he will break the bank in Dallas.

With that in mind, how much is tailback C.J. Spiller worth to the Buffalo Bills?

Buffalo's former first-round pick is an unrestricted free agent coming off an injury-plagued season in which he rushed for just 300 yards on 74 carries. Spiller tied a career low with 3.8 yards per carry, and didn't score a single rushing touchdown in nine games. Still, the Bills intend to make a push to bring Spiller back next season.

Spiller had his best years in 2012 and 2013, when he rushed for a combined 2,177 yards and 10 total touchdowns. Those will be the seasons Spiller's representation points to when negotiating his value.

However, Buffalo has the market in its favor. Running backs are one of the NFL's most disposable commodities. Last year's top free-agent tailbacks -- Ben Tate (two years, $6.2 million), Maurice Jones-Drew (three years, $7.5 million), Darren McFadden (one year, $4 million) and Knowshon Moreno (one year, $3 million) -- all received team-friendly contracts.

Spiller most likely will get an offer in the range of these aforementioned players, who average between $2.5 million and $4 million per season. Also, expect the Bills to keep an eye on the situation with the Cowboys, who will set the top of this year's tailback market with Murray.

The Bills should be careful not to overpay for Spiller. With new head coach Rex Ryan and offensive coordinator Greg Roman, Buffalo will be a power-running team in 2015. That doesn't necessarily fit Spiller's strengths. Therefore, paying Spiller top money wouldn't make a lot of sense, especially since Buffalo has other needs to address this offseason.

The franchise tag is projected to be about $11 million for running backs in 2015. So that option is out for Spiller. Soon-to-be-former Minnesota Vikings running back Adrian Peterson is the highest-paid player at his position with an average salary of $9 million per year. But those paydays for running backs appear to be in the rearview mirror.

The Bills-Spiller situation will be another interesting case study for free-agent running backs. Look for Buffalo to make a push for Spiller, but only within reason.
