This is a very interesting league with the combination of one keeper and deep starting rosters that ultimately require three starting RBs and WRs. Overall, I think you did a good job of assembling a competitive team, especially at your non-flex positions. I am not a big fan of BGE or Hines Ward as starters, but recognize the pickings must have become slim at that point.
I also saw your note about defenses being more valuable in this league, but I disagree. Defenses are too volatile to spend a 7th round pick. I don't know what was available at this point of the draft, but I would have gone after another RB or WR at this position instead.
No matter what, your team is likely headed for the playoffs. Just make sure to be active on hot pick-ups and you should be able to improve your flex position. Good job drafting a competitive team!
Please take a look at my league when you have a sec. I'm trying to get a cafe consensus on who had the best draft (probably not me).http://www.fantasyfootballcafe.com/forums/viewtopic.php?f=44&t=495050
