Here is when you start to worry about Jansen leaving or Dockery going elsewhere:

Stories start to appear in the Post and the Times and on Triple XXX Radio about how Jansen and/or Dockery is stubborn and/or not amenable to coaching and/or annoying to his teammates and/or has bad body odor.

That's what the Skins do when they are about to cut ties with players that have been around for a while; they trash them in the press to "soften the blow" for the fans. None of that has happened yet.

If it does, then you can look for the named player to be moving on...
