I think the popular theory is it would be one or the other, with neither being more likely than both. The presence of one would make it less attractive to the other. These two guys will be able to pick from any number of really good opportunities to play early, often, and win.
As far as the backup PG discussion, I bet they find a graduate type player to provide depth for this season only. With the sheer volume of players in the portal, the game of musical chairs will leave some guys without a seat. The freshman talent we have coming in at that position is going to make it tough to land one of the highly discussed PGs in the portal. Obviously, I'd love to be wrong, but if I were say, Courtney Ramey, I would not want to compete with Skyy and Epps for minutes. By the end of the year, I might be spending a lot of time in my warmups... As scholarships become more scarce, I think we will find an insurance policy.
