The NFL has the tape now of the "strong person of interest." Patriots win the SB and the tape nails them, the NFL isn't going to have any credibility. "We took our time to watch the tape?" Good luck with that. The NFL is taking a lot of flack already. They can't sit on the tape if it's the smoking gun.
Thus, unless I assume they're dumb as rocks, the NFL doesn't have a smoking gun in the tape.
Baby steps. At least they will have watched the tape this time.
Yeah, the NFL doesn't do so well with tapes. First, they destroyed the Spy Gate one. Strike 1. Then, they didn't watch the Ray Rice one. Strike 2. Now, they're going to just sit on this one.
For all the blundering, though, it's not harming the bottom line, so why should they change?
