This site I subscribe to. Division1a on there isn't staff but he said he used to work for Rivals, and gives out tons of information on there that has so far been pretty accurate. He says he has a relationship with both Arik and Shaq and talks to them on a regular basis.
Here are some of his quotes.
"AA and Shaq are meeting right now..."
"Sorry for the delay guys. As you know, the Armsteads are family to me. So there is only so much I can say. I'm not the type to cross boundaries and ruin relationships over breaking news that the family wants to stay confidential.
What I can tell you is that Chip Kelly wowed the family last night. They also liked Pellum a lot. Chip was very honest and set out a game plan that he had for Arik.
In my opinion, Oregon is in the lead with Cal. I have no idea who it will be. Oregon has a great chance here...But this is recruiting, and Cal is the home school.
The Armsteads will take a few days to think things over. I'd expect Arik to reach a decision in a few days.
In regards to the visit with UW, that also went well. But as I've said many times, they aren't a real player here.
This is either Oregon or Cal."
