Haley loves McCluster and at $1 I would not be able to say no! He is very talented and really the only game breaking option they have to run the ball. I see McC getting 12-16 touches (6-8 receptions) and breaking some big plays. The Chiefs have nothing to lose they may as well see what they have in the youngster. Plus this offense already had specific plays for McC and he will pick up a ton of screen/sweep plays designed for Jamal Charles. Big upside here especially with the WR/RB eligibility.
I think for the price you should grab one of the KC backs. If McCluster qualifies as a RB/WR in your league, you should grab him for $1. Having the option to be able to put him in either spot is nice. If not, I like Jones for this year. I think it wise to grab another QB as well. You have to great young options, but there is no guarantee that either one will be a hot hand on any given week. I'd pick up Freeman.
i would get Fitzpatrick before Freeman, and will get you more points too. my 2 pick are also Fitzpatrick and F.Davis
correct me if i am wrong, you said you have $31 extra now since you put Charles in IR and there's no cap on how many player you can have, therefore, can't you just grab all the players you have listed? (all of them together is less than 31 or close to 31 i would assume) not sure how your league works.
My rankings of who is available to you, deleting those I wouldn't bother with...
QBs J. Freeman ($5) R. Fitzpatrick ($1) -both great options
RBs T. Jones ($1) -could defiantly use to help your RBs out immediately, however, will diminish over time
WRs A. Collie ($6) D. McCluster ($1)
TEs T. Gonzalez ($2) - It's only been two games, but comeback player of the year? F. Davis ($1)
You have a lot of great options out there for a 12 man league, try and utilize it! The rest is really up to you, If this was my team I'd probably grab T Jones, but the value of Freeman and Fitzpatrick is very tempting, I like them both better than Bradford.
