I'd like to know your scoring system. If Qbs are scored like most leagues I think you could afford to trade or drop one for depth at RB or WR. If they are scored highly then it was smart to stock up.
Not crazy about your 3rd option at RB. Brown has the potential to star in Indy but Addai is pesky and won't concede that starting spot easily. Hightower will eventually give way to Wells, probably sooner than later. Maybe you could sell high on him while he's still labeled the #1 in Arizona. But your starters are solid.
Again, two great starters at WR. If Floyd takes over for VJax then you'll have a great option at WR3. Mason isn't bad either--very consistent.
Cooley looks great so far and I think he could be a poor man's Dallas Clark this year--and that's a pretty good thing to be.
Keep an eye out for trades or free agents who could bolster your RB & WR depth--guys like Arian Foster, Mike Williams in Tampa...players like that are always available.
Good luck, and please see mine:viewtopic.php?t=469277
