Stefan Adams, was in my opinion, not just guessing concerning the Applewhite situation.
Reporters develop and vet sources who they trust. In this instance, the source(s) may have very well been sharing information that was accurate at the moment they were passing it along to Stefan. But, as only one example, an hour later Miami's administration may have spoken with Applewhite's people who asked for something additional that was a non-starter or they simply decided not to fulfill their commitment made during earlier negotiations.
Most importantly are the following highlighted words; "Major Applewhite will be the new offensive coordinator at Miami, multiple sources tell CanesInSight.com". "Multiple Sources", which leads me to believe an unexpected change occurred after Stefan received the reported information, thus doing his job, he simply reported what those close to the negotiations believed to be true at the time.
This is not even in the same Universe as those numerous absurd reports submitted as incontrovertible evidence by rivals concerning Al Golden.
