Based on your team in SIG, I would use Buch, Meier, and Darling as full time claim positions. Use those three spots to max GP each week. If you cant find 3 players that beat what you have, skip forward to the next week. With no trading your best chance at winning is working harder and smarter on the FA pool than any other GM.
As for the list above, they only matter if you think they can become a regular and will be worth giving up a stream spot for or losing Gallagher or Zucker for. Eberle and Johansen jump at at first glance. I think to really succeed you need the full 3 stream spots though so you got to decide if you like either more than the two mentioned above. Besides that focus on GP per week. Its just too many names for me to research for next week though (at mall right now), but I think all but Marleau, Patrick, Konency, DeBrusk, Bjugstad, and Brown would be solid players to claim if they have 1gp or more in a week than your bottom forward starter on said week. Some of the kids need time for us to see what role they are in this year.
