Grantland: Bill and Jalen's Celtics preview

Grantland's Bill Simmons and Jalen Rose are back with a breakdown of the Celtics' upcoming season that includes a potential trade sending Rajon Rondo out of Boston and a revelation that Jalen used to routinely deface the Celtics' home floor as a tribute to Larry Bird, all with the help of the Doobie Brothers. Lots of help from the Doobie Brothers.
