Johnson was making claims about what happened 17 years ago. Without any substantiation whatsoever, much less for any claims of Mudd continuing to do it since that time.
And the playoff game proved...what? The Colts ran the no-huddle on the final drive of the 1st half and noticed the Patriots' defense was tired-out by it. So they ran the no-huddle in the 2nd half and scored at-will. It didn't take stealing signals to figure that one out, pally.
Or are you claiming that "Slow Tony" illegally videotaped signals as well? Well then, why didn't Belichick finger him, or any other coaches, when he got caught? Wait, let me guess: it's because he's too classy to do that.
Again, it goes back to JJ's "credibility." No wonder you have a problem with it.
And if he really cared about "tarnish[ing] his own reputation," he wouldn't have admitted that he had guys fishing through garbage. And it's not like anyone can do anything about it now, like take away his rings, the money he's made and fame he's achieved as a result. It's little different than Alex Rodriguez saying "yeah, I took steroids with the Rangers, but I'm clean now (and you can't do anything about it)."
