Superstar guard? Maybe you mean Rodriguez? Rodriguez is a SF. Superstar guards would need a very specific build, agreed.
MVP guards can make it, Ritter and Dennison are good examples of MVP guards who have contributed to the NT. Ugona is HOF, but is less than MVP salary. They probably won't reach Bronson levels but yea plenty of MVP guards in contention.
MVP bigs on the other hand...unlikely at this point, would have to have an interesting SF/PF type build.
I'm too poor and/or picky. But mostly poor
Your avatar is the Wall Street Bull, I refuse to believe you are poor. Not only do I demand to see your birth certificate, but I further demand to see your tax returns.
