Looks like a decent team.
TRich should be in you starting lineup. I would play him over Bush. Nice to have all those options at running back.
I would play Colston over Lafell for sure. I would actually even play him over Dez, but put him in for Lafell.
I might take Owen Daniels over Fred Davis, but I think its a close one.
You do need to add some WR help, but luckily there should be some decent options on the wire. Not thrilled with Roberts considering the woeful state of Arizona's offense, but it might be a decent add for you. I would certainly be scouring the waiver wire for WR help though. Some potential targets: Donnie Avery, James Jones, Jeremy Kerley, and Leonard Hankerson. See whats out there.
