'Move on' was a poor choice of wording. "Prepare for a plan B" is more appropriate your right. The thing is though, two of the others recruiting Diallo are the types that don't really have "plan B's" because they rarely need them.
Both of yours are good posts, but I still think you're offering an ungenerous take on the Diallo situation for a couple of reasons:
1. If a local-ish player like Beatty or Randolph comes onto the scene out of nowhere, and we can be one of the first big schools to offer, that's just smart business
2. If a 5-star wing like DJ Harvey has serious interest in us (and he certainly seems to), of course we're going to go hard after him. There's been no time in program history when we've been able to say "naw" to a top 25 recruit
So I think we'd have been offering these guys no matter what -- even if Diallo had already committed, KO would find room (and that's without factoring in the harsh lesson of the Ali decommit).
Re: Big men, I'm not sure I agree that we'll need to load up. Going into the 2017-18 season we'd likely have Enoch, Durham & Diarra who are all 4/5s, and Jackson who's a 3/4. I suspect we'll try to add Richards (a pure 5) and someone like Deng Gak or Makhtar Gueye, a DeAndre-type stretch 4 who can guard 1-thru-4 and protect the rim (obviously they'll need much more development, but those are the raw tools). That's a pretty loaded front court
If that happens, and we land Beatty & MAL, that'd still leave us one spot for Harvey or Hamidou. And if
both want to commit... I'm certain KO could find a way. Gak/Gueye aren't exactly essential gets given the potential roster make-up.
