Is my fantasy football team good?

None of your players are bad, but other than Chris Johnson and Tom Brady, you don't have many players that are top tier. Wes Welker is pretty good but no WR1 quality, and Felix Jones is more of a risk/reward sleeper than an RB2. Desean Jackson and Bernard Berrian have good potential but aren't starter, or for sure not WR2, caliber. I would say 3.5/10 for a ten team league, a 4.5/10 for a twelve team league, and 5.5 or 6/10 for a fourteen team league.
