I've been hearing that they have to go through waivers before becoming a UFA. I'm trying to find an article to showcase it but honestly can't. I could be absolutely wrong though
No, I believe that was a one-off thing before the start of this season. Summers 2013 and 2014 any compliance buyouts go straight to UFA.
And for the record, Marian Hossa's highest goal total in the last 7 seasons was 40 goals in 2008-09.....when he played with Pavel Datsyuk.
