Welcome to the Cafe!
It is tough to judge rosters in leagues that are somewhat smaller. Every team is starting top options, so sometimes it just comes down to matchups. Any given Sunday, right?
With that being said, I'll do my best to rate yours. My first thought looking at your roster is that you are very strong at WR and a bit weak at RB. Your top options are good, but if you could upgrade at all over Kynch that would complete your roster. In standard scoring leagues I always want to start as many RBs as possible. I think you could possibly turn some of that WR depth to land a more solid RB2 or RB3 to play in your RB/WR slot. I would look to move either Miles Austin or Brandon Marshall to a team that needs wide receiver help. Calvin Johnson will be a solid number 1, and Maclin, Harvin, and even Mike Thomas will be productive throughout the year to compliment him.
Good luck in 2011
