Fantasy football playoffs redraft strategy

You obviously have to try and get Manning, but he may be gone when you pick. If you do get him, then your next targets are either Decker or Thomas. Depending on how many Broncos you want, I'd try to get Moreno or the kicker. You should also have a backup plan in place. I would think that the first three picks (in some order) will be Brady, Rogers, and Manning. If Manning is gone when you draft, then I'd try to load up on New England. Green Bay has so many different targets that it's hard to know who will have a big game for them.
If you do end up with Rogers, then you will have no problem getting one of their receivers in a later round.
Don't reach for a player though, just because of his team. For the most part, take the best player available.

If you take Manning and either Decker/Thomas, then the kicker and/or defense are also acceptable. The one problem with taking Manning, WR, AND Moreno is this: QB/Receivers work well together as they obviously can both have big games. When you take a RB with them, most likely one will go off, but one will not. (I'm talking running vs. passing game)
A much lower risk and potentially higher reward strategy would be to take someone like Lynch. I really like him this week and think he will get many carries with a good chance of a TD or two.
If you want to load up on Denver, I would stay with a passing combination and the defense and maybe the kicker.
If you're looking for a good TE option, I'd take Gonzo. Seattle's cornerbacks are outstanding and Ryan may look to Gonzo more than usual as Julio and Roddy may be neutralized.
After that, I'd pepper in other players with good value. Other players I like this week are Crabtree, Gore, and Ridley.
TIFWIW, but I have won our league's title 9 times, with the next closest person at 4. I also finished in the 99th percentile last year in the ESPN playoff Gridiron Challenge and am at 98.4% after the first round this year. Good luck!
