I clearly doubt Rondo would resign with them, so I don't think that's a possibility.
Only two teams I could see Rondo going to and staying there are Lakers and Rockets. And I don't think Lakers have enough to offer for a player of Rondo caliber. They will only have 3-4 players staying on contracts this summer and, of course, Kobe's not going anywhere.
I certainly hope we give Rondo a shot to showcase his talent next year with some good talent. This years team stinks.
