I'd say pick up Bell for at least this week, keep an eye on J.Davis in Cle also. If I had those choices I might go with LJ, tough matchup though. Fred Taylor was named the starter in NE but that really doesn't mean a whole lot, didn't know if you knew that or not, just read it today myself (hate NE 4ever)
I hate to say this, but I've picked up LJ in a league this year and will start him at flex this week over Bell. KC has to go to someone and he'll be getting short passes as well as carries. Bell is the safer start, however.
I'd say it's a toss-up between LJ and Bell. If it costs $ for a WW transaction in your league, I'd stick with LJ. If WW are free, it could be worth it to add Bell. He should have a solid week, most likely a short TD. Can't say I see that for certain out of LJ. Thanks for your help on mine.
Man, I guess I need to pick up Bell...we have a 20 move limit for the season so I need to assure that I'm making the right decision on each and every move. Any other suggestions from anybody? WHIR!
