It is against the rules to watch video replays on the sidelines of the current game.

These tablet solutions are simply showing photos, which is replacing the paper version of printing out photos.

I can understand why a complicated tech solution that doesn't work reliably 100% of the time is essentially useless compared to a 100% reliable printed picture, solving the same use case.

Per Belichick, the NFL was experimenting with video on the sidelines.

Was that mentioned in this article? I don't see it. So his tablet use currently was for still photo viewing.

Here[0], we see that experimentation with video has only occurred during preseason games. So, in the games that actually matter, video is still currently outlawed, as it has been forever.
