that is my strategy in a 12 teamer with all TDs being 6 pts. In an 8 teamer with 4 pts, you may be OK getting one of the top 7, and then one from the next tier.
I would tr to get a TOP 5 guy and then wait for McNabb,Young types as your #2. If you can get Brees/Rogers types then Cutler,Rivers I do that back to back picks 100%.
