It's a no-brainer. Take Rice. Cutler has recently found himself in the unfamiliar position of being a replaceable dynasty asset at QB, and Wells flashed a little bit of talent, but ultimately just finished a mediocre rookie season that saw him fail to break 800 yards rushing or relegate Tim Hightower to the bench. Wells' upside is lower than Rice's current reality.I'd also like to take this opportunity to point out that there's no such thing as a "stable fantasy RB2" like there is at WR. Few guys ranked in the 10-20 range at the beginning of the year find themselves anywhere near there at the end of the year. A very small percentage of them will step into the top 10, but by and large, they tend to just fall off the map.
Witness F&L's RB rankings from September 9th, 2009, specifically the guys outside of the top 2 tiers. The RBs ranked from 9 to 24 were, in order: Moreno, McFadden, Ronnie Brown, Jacobs, Kevin Smith, Slaton, BarberIII, Wells, Lynch, Stewart, Rice, Felix, Pierre, Tomlinson, Westbrook, Portis. Of those 16 RBs, I count two that F&L has in a higher tier today than he did at the beginning of the season (Rice and Stewart). Well, technically 3, because Felix jumped from the top of Tier 4 to the bottom of Tier 3, but his arbitrary value score only went from 60 to 69- not a meteoric rise by any stretch. Three other RBs managed to finish in the same tier that they started in, but two of the backs (Moreno and Wells) only managed it because of their pedigree and youth, rather than because of anything they did on the field. The third RB (Pierre Thomas) only managed to retain his value because he had so little value to begin with- he went from 21st to 19th despite seeing his value fall from 59 to 56, just because everyone else's value fell even more.
That leaves the bulk of the RBs- McFadden, Brown, Jacobs, Smith, Slaton, Barber, Lynch, Tomlinson, Westbrook, Portis. That's 10 of the 16 backs in question, and they all saw their value take a catastrophic swan dive. Many of them (Barber, Jacobs, Smith, Slaton, Lynch, Portis) looked like the kind of dynasty assets that you could count on being an RB2 for a while to come, but the reality is that RBs turn over too quickly. There really aren't any "perpetual RB2" guys out there, guys like a Santonio Holmes. For the most part, if you're not already considered an elite RB, one of two things will happen- you'll either make the jump and become an elite RB or, far more frequently, you'll fall off the map with surprising suddenness.
Right now, Wells finds himself in that uncomfortable ranking range. Personally, if it were me, I'd be trying like hell to leverage all the RBs I have in that range in order to try and move up to grab an elite talent. Instead of a bunch of 10-16 type RBs, I'd rather have a single top-6 RB and a handful of prospects, longshots, and 20-30 type guys. The 20-30 guys often carry just as much potential for reward, but with far less cost. If I owned your team, moving Wells for Rice is
exactly the type of move I'd be working hard trying to make, and the fact that another owner actually approached YOU with the deal (and the fact that the upgrade only costs Cutler, a very expendable asset) only makes it that much sweeter.
