This is a very solid team.
Your greatest strength is at wide receiver. You have 3 number one wideouts in Reggie Wayne, Hakeem Nicks, and Santonio Holmes. Top WRs are awesome to have in full point PPR leagues, especially ones who look to have decently high reception totals.
Ray Rice is also PPR gold. Ricky Williams may be replacing Willis McGahee, but Rice has top level talent and will be the main focus of the Baltimore offense. Jahvid Best's upside is through the roof in PPR leagues now that Mikel Leshoure is out for the year with an Achilles' tear. He has a chance to break out in a major way if he can stay healthy in 2011.
The 5th round does seem a tad early for Matt Ryan in my opinion, but he should be able to build on his 2010 year. The Falcons drafted Julio Jones to compliment Roddy White, so Ryan has a decent cast to throw to.
I don't really love rostering two defenses at a time, but that is just a small nitpick. If there is any flier at RB or WR worth owning I would lose the Cardinals for a shot on them.
Good luck in 2011
