I'm not concerned about the eighth option, and while I wouldn't use the word "crazy", I would say it's "risky" to expect a #27 recruit to be our fifth option because not many freshman around #27 were good enough to be the fifth option on a really good team last year. Arizona, UConn, and Florida all had guys in this range, and they were #8-9 in minutes played. That's saying nothing about Coleman himself- he might be great and people said much worse things about Keaton last year. It's just my perspective on roster risk.
Bringing in a star (or anyone meaningfully better than Jake) and planning for Jake & Coleman to come off the bench would be an upgrade (at least regarding risk; nothing is guaranteed). Without that, Jake is our "floor" if Coleman needs more time to adjust. And that's not a bad option, but it just adds more pressure for our top four to take bigger steps forward if we want to reach another level.
If we tried and/or are trying to get such a player, then it seems like the staff at least agrees that there's room for an upgrade. If they can't find the right player who wants to come here, that's a bummer, but it doesn't mean wanting more is crazy either.
