From what I had read various places, info coming from people who would have some reasonable way of knowing (if only via premium subs to beat writer content, I mean who knows), Sarr's agent raised the sticker price nearly every time Illinois had a conversation with him.
Originally they were talking in the $1.25 to $1.5 M range. Duke got involved. Oregon got involved. Miami got involved. Couple others too. Agent also used the NBA Draft as leverage when he started getting rotation minutes for Barc A team (i.e., we will stay out of the draft if you commit to paying us this number right now, etc etc). At some point his agent was asking nearly $4 M (I also understand we had given up long before the number got there).
Illinois took Andrej, Duke took Coward, Oregon took on Simpkins & Pryor (although they still may be involved, not sure), Miami got Allen & Malovec. Then it's become clearer that Sarr isn't going in this year's draft, he isn't welcome back with Barcelona, so on and so forth.
Given how this seems to have played out, have to imagine his entire camp is in absolute shambles right now lol.
