According to this, only 11 teams have the cap room to claim Ryan's $3.125M cap hit:

This excludes LTIR, but IIRC that doesn't kick in until the season starts so I'm guessing that is why he got waived today.
A lot of non-playoff teams, but if you're looking to plug a gap with a reasonable player with only one year left on his contract, there could be a fit. The question is whether you want to develop someone else in that spot, or perhaps sign one of the many UFA's still out there (whom you could likely get for the league minimum).
I suspect he won't be claimed.
