As Roy and CIO said, the rift story occurred last year.
Also, the beat guys do not watch the games at home. Who do you think is asking all the questions in the post game interviews? If there was internal problems going on in the lock room, the Boston media boys would be all over it. They were, after all, the first to report on the anger throughout the franchise towards Big Baby after he broke his thumb. And given the recent local stories from the Boston media regarding KG praising Rondo and Ray and KG talking to Rondo after his missed FTs, I think the Bucher story is 100% completely bogus.
