I can see why there is discussion about rumors and commitments causing confusion...
On the RU scout premium board, there was a post by an administrator that Syracuse was in the lead for Zach, this was on Tuesday at 7:24am
Since it was premium I guess the Scout sources there did not leak out onto your board here
so RU fans on the premium board were aware that he visited Cuse, and the visit was probably over the previous weekend.
But no post on the free board about it.
Of course, information comes out at different times, sometimes here first, sometimes elsewhere.
To further confuse the issue, supposedly scout then had an erroneous article on him committing to Syracuse, and that was quickly taken down.
Edit: I also agree that his chances of starting at RU are much greater and was the deciding factor.
