Well, that's what I think is the most realistic thing.
Get a good big in. Either of these guys works fine. Then i'd get a big via transfer and go back to the drawing board next year to try and get that major commit from a real impact big man.
You'd be looking at two top-100 guards, two top 100 front court guys and a transfer who hopefully rebounds/protects the rim and I think with some improvement with everyone else, you're making this a better team in theory.
And you're also saving a scholarship to get that guy you really want. It could be a big difference in year-3 when you've got a fully matured Gilbert/Wilson and a growing Akok/Bouknight/Gaffney with some parts.
At that point - what happens with Carlton in that time period happens. If he gets better, then that's fantastic. If he doesn't, whatever.
