"unnamed teams" ussually indicate something being floated by an agent. I wouldn't put too much stock into it yet. It sounds like scare tactics to me.
My thoughts exactly.
James: "Maybe I should take the three year MLE from BOS."
Agent: "No - someone will offer four years - you are a proven veteran winner. I mean the Celtics were 2nd worst team, you come onboard, they win the championship. You gotta get paid."
James: "Okay - get me for MLE at a contender and I'm in."
[Days Later]
James: "Where are the four year offers? Call me back."
..
Agent: [muffled voice] "yeah this is [mumbles name] - there is a four year offer on the table - I swear."
...
Agent: "James - did you hear on EEI - a team is offering four years."
