NEWPORT, R.I. -- Five observations about the Boston Celtics coming out of their training camp this week at Salve Regina University:

1. Rondo: Why did they consider trading him?

General manager Danny Ainge has acknowledged discussing possible Rondo trades with other teams early in the offseason (one proposal that was floated but never gained traction was a multiplayer deal that would have included Devin Harris of the New Jersey Nets), but he is now saying he would like to see Rondo show the type of increased maturity and leadership -- both on the court and in the locker room -- over the course of the season to ensure he's worthy of a contract that would keep him in Boston for the next half-decade.
