Here's what does not add up to me. Coaches tell Kai they think he'll make a better fullback than OG or C. Kai discusses with his family, decides to take the challenge and embraces the move (as reported in all the papers).
Spring ends, and his learning curve is not quite as steep as it once was expected.
If he was really that unhappy, wouldn't he go back to the coaches and say so? Would Hawk respond to Kai's request to move back to OL with "its fullback, or the highway"?
Perhaps I'm being naive, but that does not jive with Hawk's style.
Also, there is nothing preventing the other OGs (Bahr, Faatagi, Iltis, Behrens, Daniels) - all of whom redshirted or (in Faatagi's case) were ineligible last year - from beating Kai out this year. Kai was not guaranteed PT on the OL either.
So, if (and that's a big IF) he decides to leave because he's not getting enough PT at the FB position, would he have done the same if he had been beaten out of the starting OG spot? That doesn't jive with Kai's personality.
Either this report is 100% Bull****, or there is something else going on that we don't know about.
