Assume Ostrom goes to IU. I actually think not only bad form if they try to take recruits to IU, but potentially worse.
If the Minnesota article was correct (it later was modified) that Wright was told that he had a place at IU if he wanted it, some different possibilities exist. If Archie was still under contract at Dayton, you have breach of contract and fiduciary duty issue. If Archie was under a MOU or contract at Indiana, you have a recruiting violation. There could be other possibilities and again this assumes the article was correct. It is unlikely IMHO but not implausible that Wright created the story that he had a spot at IU if he wanted it.
Also when Archie was on the radio interview and asked about Wright, he pushed Dayton too much. I was reminded of a Shakespeare quote, doth protest too much (when you protest too much, it is probably true). My PURE SPECULATION (and I cannot emphasize enough this is speculation with no factual basis or evidence) is that Archie heard of the article, now is trying to backtrack, and will not offer Wright as he does not want to start his tenure at IU with a recruiting violation investigation.
But I also think that Wright and the Czech recruit will not be at Dayton next year (again pure speculation with no evidence) Hoping for 3/5 and would be happy with 2/5 staying.
