This rumor is NOT NEW. This has been going around for at least a month.
I Love Rondo. He is, without a doubt, the best transition point guard in the NBA and its really not close. His fast break court vision and decision making are things of beauty. However, he is a big time half court liability and the rest of the team can't run with him. They are too damn old.
If they Lakers put the right pieces around him, he really could bring Showtime back. He is a special talent, but his jumpshot/freethrow flaw is a big one.
The Celtics do it, because they don't want to build around Rondo. They don't want to face the free safety for the next 10 years. With Gasol, it makes them a contender THIS YEAR. This Boston thing is going to be totally blown up very soon. It makes a lot of sense for both teams.
Don't forget, Gasol is still a very tradeable a.sset. I could see the Celtics using him this year and then looking to move him. Houston is still dying to have him. Sometimes you make one move to make another move. Its Chess not Checkers.
