OMM, as was stated, this wasn't an impulsive decision on his part. He had the offer, and took weeks to make a decision, whereas Cam decided right away (on the surface, much more of an impulsive decision).
The thing with Okatcha is that he NEVER talks to the media. So not hearing from him could be a bad sign or a normal sign; nobody knows.
He did say that only 2 schools would get him to think about opening his recruitment...ND and Oklahoma. Both came calling, and he chose ND. OK recruiting him is nothing new...he chose ND a couple months back and I believe he'll choose ND on NSD.
But then again, it's recruiting, so anything can and will happen...
