This section from Belichick's statement is KEY, especially the second sentence.
“As the Commissioner acknowledged, our use of sideline video had no impact on the outcome of last week’s game. WE HAVE NEVER USED SIDELINE VIDEO TO OBTAIN A COMPETITIVE ADVANTAGE WHILE THE GAME WAS IN PROGRESS."
So does that leave open the possibility that BB considers halftime to be a time when the game is "NOT" in progress.
And if they used the tapes for future games, what was the purpose of taping the Green Bay game last year, a team they play about every 6-7 years?
The rule states very clearly, " no use of video". Everybody needs to let it go. It doesn't affect the team at all.
