Look, I have no doubt you have good intentions. My reference to "juvenile tone" refers to the kind of statements of absolute certainty....the "we out" or "he's ours" sorts. I don't mean it necessarily as a reference to immaturity. When I do get some interesting information from "inside", it is rarely of the absolute kind...usually its along the lines of this guy is in trouble academically, or this kid is really coming on strong in practice, or even this coach is is not really fitting in with the rest of the staff. I've yet to be told something as specific about a recruit as "we out"....because most often even the coaches aren't 100% sure where they stand.
Its certainly possible that Diallo called Coach Hoiberg and told him that ISU is out....and that you then heard directly from FH, or an assistant...that we are 100% out of it. But that just feels unlikely, even if you do have a good source. Maybe I'm wrong and Coach Hoiberg called you personally to tell you "Diallo says we're out"...but, yes, I'm skeptical of that.
If I've offended you with my skepticism, that's not my intention....I'm trying to explain to you why declarations of "certainty" generally meet with disbelief. Most likely, Diallo goes to KU/UK/St John's and this whole discussion is rendered moot, but it just feels over the top for anyone to assert they have infallible knowledge of this at this point.
