Your QBs are strong, you can't go wrong with Brees and I think Rodgers is going to have another great season. I think J. Russel would be a better qb if he wasn't on such a POS team. He's got virtually no targets in Oakland and if he hasn't been able to get a rushing game going thus far, he probably wont. You usually see successful rushing QBs in their first year in the NFL bc defenses don't know what to expect. That never happened for Russel.
If your RBs have a good year you should be ok. Grant and Ward are risky bc Grant had a lackluster season last year and Ward is with the new team. Stewart is fantastic but in the committee with D. Williams you never know. Jones, Taylor, and Maroney are all up in the air this season, I believe.
Andre Johnson is really your only proven WR. Eddie Royal is great but he's still the #2 guy behind Marshall. For your sake, lets hope Marshall gets released/traded/suspended indefinitely/ or something so that Royal can really shine. He'll def get some TDs but I personally don't feel like he'll be breaking the 100 yd rec much during the season. Coles is sort of in the same roll as Royal. Hixon is the new big man in NY and has some really good talent... but he's also a little too unproven. Branch has big talent but he's always injury prone.
You can obviously never go wrong with Gates and as backup, Winslow isn't bad. Especially if he has a decent qb throwing to him.
