Again, people have trouble comprehending. Not you guys. The media.
Belichick told Goodall about all the taping he's done. We assume he told the truth. Goodall said the tapes just had stuff from 2006 on. Those two statements DO NOT mean that Belichick said he started taping in 2006. He likely told Goodall he's been doing it all along and re-used tapes when the analysis was done.
For some reason, people have decided that the fact that Goodall said the tapes were from no earlier than 2006 means that any taping prior to 2006 is "new allegations against Belichick". However it's not, assuming that Belichick really did tell Goodall everything.
