First off, the trade is a technically fiscal impossibility.
Second, no. I haven't seen Jennings play but I still believe heavily in Rondo, regardless of his up and down start to this season and the rash of hatred coming from the fans of the Celtics placing a majority of the responsibility for this team's recent woes squarely on the shoulders of Rondo. He is part of the problem but not the problem.
If I remember right, even through the C's great start last year Rondo played rather sketchy ball for a period of about ten games after starting out good. From that point in settled into an All-Star quality caliber of basketball for the rest of the season. If history does repeat itself, Rondo's game is about to become awfully good.
