Do you play in many leagues that use non-basic stats? Previously when discussing Foster you said that all that matters is production. Charles and Rice have similiar ultimate production.I love Charles as well so I'm not really debating Charles v. Rice.
Don't take this request as being a wise guy, but did you find any stats that back up your claim above that Rice is a poor short yardage back like I asked above? I still haven't found anything to show that either way - but watching him play a lot in college and the pros tells me that he is effective when the opportunity is there.
I actually haven't found the stats, but I did look for quite some time. It is amazing how advanced NBA and MLB stat keeping is compared to the NFL. I am basing my statement on a graphic (CBS, I think) that showed last year that stated McGahee was twice as effective on 3rd/4th and short than Rice was last season. Because I don't have the specifics, I won't use that. I will simply say that based on what I have seen, Rice is not great in short yardage situations. Simple Redzone stats (3 carries, 3 touchdowns = 100%) don't capture this as they do nothing to analyze the individual situations each carry takes place in. But, to answer your first question, no. None of my leagues reward advanced stats. But they are a great light to hold dynasty prospects up to, one that goes far beyond basic stats. All that matters is production and advanced stats are only a more specific, in depth evaluation of production. For the record, advance stats show that Foster is playing as well, or better, than his numbers suggest.
As for your ultimate production (Rice = Charles) comment, that only applies in re-draft formats. Production measures show that Charles is the better player, and does more with each touch, meaning, Rice is far more dependant on his carry load. If that changes, so will is production.
Charles, on the other hand, is in a situation that is more likely to change for the better, while Rice is currently has a full load.
In other words, Rice needs the ball a lot more to match Charles' ultimate production. It is not safe to predict that trend (number of carries greatly favoring Rice) so it definitely matters.
