I think if they were inside the wild card we don't see these moves take place, regardless of how little impact it has on the team. Drury wanted to make a splash early in the season and it back fired on them. The plan wasn't to just sell all UFA's because guys like Riley Smith aren't players you worry about losing for nothing. Getting further and further away from that wild card spot, Fox getting injured, and watching other teams continue to win definitely pushed them into acknowledging that it's not likely this season.
He's not taking 5M of the cap, or costing any team 5m in salary.
