I wouldn't try to read too much into any of these so-called signs:
(1) Offering two more OL
(2) Waiting to confirm commitment
I don't think either of those events are indicitive of him being a Hawkeye/Badger or a Gopher. Like another poster said, he is wanting to call every other coach he considered and tell them in person that he isn't interested. At this point in the recruitment process, if they miss a call, they can't call back, so Jonah (and any other prospect) has to keep calling the coaches until he catches them. So that's why it sometimes takes a little while.
As far as Carlos, I don't know what to think. He is an Iowa fan and his name keeps reminding me of Carlos the Jackal, so I don't really trust anything he says. I don't want to call anyone a liar, but, I don't really think much of his prediction. I hope in a couple days I can sign on here to apologize to him for not entirely believing what he had to say, but i'm skeptical.
That said, lets go Jonah, make the right decision. You can join one of the better in-state classes this state has ever seen and 3ish years from now you can be on a Gopher team, dominated by MN kids, that is competing for something big.
Either way, good luck to ya. I said the same thing with Seantrel, i'm not going to blast a kid for not coming to the U. It would be disappointing, and I truley think it would be the wrong choice for him.
