As much as I like to bag on Burke and Exum, fine going forward with those two at the 1. Exum is a good defender, and Burke can get hot and can score.
History tells us that it's not all that important to have a great point guard to win. It's nice to have, but certainly not necessary. This isn't Jerry Sloan's system anymore either. Our offense isn't built around the 1.
I agree that they are sort of our weak point right now, but they have the potential to improve quite a bit. So, I say stay put at the PG position, unless some great deal for a really good point guard comes available. Otherwise, don't go spending all our assets just to mildly improve the 1.
I'd rather take a chance in another wing if we could. I know it's been talked about a plenty and decided it's impossible, but our focus should be trying to pry away someone like Butler or Leonard. If we offer a few assets, we may be able to get them to sign and trade them to us. I'd be looking for a homerun like that first, then exploring other things.
Other than that, just draft our player, nab a backup center and go forward. We will have a stacked team regardless.
