What would the plan be if they re-signed Yandle?
To stick him with Boyle's replacement? or with Girardi, Klein, McIlrath?
Who is the PP player on the other point?
It's not that Yandle is a bad player to me at least, his game can be useful if integrated properly but it's the timeline, what they have, what they realistically can have soon just does not seem to match-up with them giving out a large long term contract with clauses to Yandle, which is what he will require.
Teams do not usually make 10 moves in an off-season and even if they did more than half of those moves would turn out less desirable than imagined.
If they can sign him to something where the player and contract could be moved for a good return need be, maybe, but that is not how UFA contracts usually work.
