There is no objective reason to keep him around. None. This roster is of his doing, has zero playoff berths in a league that 50% of the teams get in, and appears no closer than they were two years ago. Actually, they appear further away.
Question is - does Terry even care enough to fire his pool boy, or is Adams really good at selling him on a (never ending) process?
If I'm a betting man my money goes on no significant changes only because they've spent years convincing me they're not a serious hockey organization.
