I doubt you are saving money on Haula. There are essentially 5 categories in the UFA market this year:
1) Haula and Soderberg, who are the cream of the crop and likely the only ones who are legit 3C's in this market right now. I expect both are getting a number with at least a 3 in front of it.
2) Spezza, Thornton, Brassard, Boyle and Koivu, who are old and may still have something left in the tank, but are effectively iffy 3C's right now. I understand Brassard is only 32, but he has really fallen off and is probably not even capable of being a full time center anymore.
3) Eakin, who gets his own category because he is that inconsistent. When he is on, he is as good as Haula and Soderberg. When he is not, then he is in the 4C category at best.
4) Richardson, Nosek, Larsson, Grant, Sheahan, etc., who are 4C's at best.
5) Granlund, Ennis, Girgensens, Gagner, Lewis, etc., who are oddly still listed as centers even though they are clearly wingers at this point.
If you are looking for a cheaper but still effective 3C this year, the UFA market is probably not the place to look... Not unless you are willing to accept the risk on Eakin, Boyle, Thornton or Spezza (who will likely be back anyways), but even a guy like Eakin may receive a legit contract this year if he has a strong playoffs.
