The watch is over ... and it couldn't have ended much worse from a perspective. The 2014 rushing Spencer Turnbull Jersey leader has signed with the , and will enter a crowded backfield that includes newly-signed and . Despite the succe s that running backs have had in coach Chip Kelly's system in the past, this move is a virtual "death blow" for a few reasons. First, let's talk about how it affects Murray, who led all running backs in fantasy points last season. The Oklahoma product touched the football 449 times during the course of the year and finished with 294.1 fantasy points. Let's do the math ... that's 0.65 fantasy points per touch. Now, let's look at the offense. In 2014, this unit ran the football 474 times, or 82 more times than Murray alone . Let's round that total up to 500 (the rush attempts in 2013) and split those carries up among the 2015 backfield of Murray, Mathews and Sproles. Murray is a virtual lock to the lead all backs in carries, so let's give him 275 of the projected 500 attempts. That would leave Mathews with around 175 carries and Sproles with 50. Now, let's take a look at potential reception totals. In 2014, runners put up a combined 70 receptions. With Sproles in the mix, Murray's opportunities as a receiver out of the backfield are going to decline. It's a fact. In this scenario, I'll project him to lose more than half of the 57 receptions he had a year ago. So, let's do the math. If I project Murray to receive 275 carries and catch 25 pa ses, that gives him 300 touches ... or 40 fewer than had last season. And I think that's even a bit generous. Now let's multiply those 300 projected touches by the 0.65 fantasy-point-per touch average from 2014. That gives us 195 fantasy points, or close to 100 fewer points than he scored last season. Once again, I am being generous with Murray's touch totals (barring injuries to Mathews or Sproles), and he's still projected to score more than six fewer fantasy points per game. Now, there will be a lot of fans out there who disagree with this a se sment because Kelly's offense generates a ton of plays and "more than enough to go around." I would answer that question much like WWE's Mike the Miz ... " ?" The already led the league in total offensive plays (1,127) last season, so how many more can he squeeze out of his team? Not enough for three running backs to sustain consistent fantasy production. Not even close. Aside from all of the stats I've thrown at you regarding offensive snaps, carries and touches, I haven't even brought up the fact that Murray is a breakdown candidate after a ma sive workload in 2014. If we look back at the history of NFL in a single season, well, the following year's production is often times a disappointment. Of the 10 instances in the era where at back has reached that mark, just one (Eric Dickerson, 1984) was able to duplicate even 90 percent of his previous season's production. Gerald Riggs (77 percent) and James Wilder (74 percent) were the lone runners other than Dickerson to duplicate better than 70 percent. Not to be a "Negative Nancy" again, but there is very little to like about this move from a fantasy value perspective when it comes to Murray or Mathews. It also hurts the overall depth of the running back position, and it wasn't deep to start. Had Murray remained in Dallas and Mathews was the top runner in Philadelphia, well, that would have been a best-case scenario. But with these two together in the same backfield, even under Kelly, would you really feel comfortable leaning on either of them in a prominent role? When it comes to Murray and Mathews, most notably the former, it's buyer beware.
