David Stern has been active on the airwaves, the Internet and, in a new one, on Twitter, trying to tell fatigued fans and an irritated set of NBA players about the need to sign on the dotted line.

Monday is the newest “most important day” of the 138-day NBA lockout. Player representatives for all 30 NBA teams will meet in New York and determine whether they will take the latest offer from NBA owners.

A majority of responses from players and their agents indicated there would be a rejection of the proposal that promised a 72-game season starting Dec. 15.

A lot has to happen this week for there to be basketball by Christmas. Stern knows it too.

The NBA commissioner lambasted player agents in a conference call with reporters Saturday and held a 90-minute “Twitterview” with players, fans and journalists Sunday, sending some final public thoughts in 140 characters or less.

He made some intriguing points, admitting that contraction of teams was discussed by players and owners but dismissed; all NBA executives took pay cuts of unspecified proportion; and players’ contracts would become void if decertification occurred (more of a threat than anything).
