First, can you guarantee me any of those players play for one of the 10 teams Horcoff puts on his list?
Second, can any of those teams afford to take salary back? Philly is a no, same with VAN.
Third, are any of those guys better options than what is available on the open market? It may not be a great UFA class, but there isn't as much competition this year either. The usual big spenders like BOS, CHI, PHI, WAS, NYR, etc are already either right up against the cap or have key UFA and RFA's to re-sign. Then you have the cap floor teams facing a similar issue. IMO you're probably looking at these teams as competition for UFAs:
DAL, BUF, CBJ, CGY, TOR, OTT, PHX, WPG and NYI. NJD are a wildcard because they have a ton of cap room but need to sign Elias, Henrique, Clarkson which if all are retained could cost around 12 mil.
So basically 9 teams that we'd be in competition with, some of them both limited and specific needs that may not affect our needs. Thanks to the 10 team list the options are far greater with a buyout than without.
