I dont see how some of you are saying LJ wont see ANY carries or only a couple. Sure Priest is a stud, but LJ has proven that either he is as well, or they both are good b/c of that awesome line.
The Chiefs definitely want to get their moneys worth out of Priest and he will be the primary back, but they also cant just let LJ sit for the whole year and be pissed and become rusty or lose confidence or whatever else. LJ should take over in 2006 when Vermeil will retire and Priest will most likely do the same.
As for other teams trading for LJ, thats also ridiculous in my opinion. KC knows that Priest wont be around after this coming year, and they know they have a very good replacement in LJ. Blaylock also did well, but LJ clearly was the better of the two. Teams are also scared of giving up too much for a RB who could be a product of the system. They saw what happened w/ Portis this year (granted WAS had a lot of injuries and he still put up decent yardage), and they dont want to get burned either.
That all said, Vermeil has never used a RBBC, but I have a feeling he will be very hard pressed to get LJ some time, especially if KC has a big lead and already have the game under control or are being blown out.
Priest will still be a very good fantasy option, but LJ is going to get some love. It wont be a 50/50 split by any means, but he will be much more involved than he was during the first half of this season.
Lastly, as for the Ahman Green and Davenport comparison, this is completely different. Priest is much older than Ahman was and is, and has had multiplel seasons end b/c of injury. I mean, Priest himself has even said that opposing D's try and knock him out of the game....why not let LJ take some of thsoe hits?
