If by similar, you mean both players fit the description of what a shooting guard should look like, then I see nothing wrong with that. In a perfect world, you want to keep both Buddy and Bogi. What it comes down to, assuming both players perform the way we think they will, is money. There isn't a contract extension on the table right now for Bogi because of the rookie contract he signed, which was for 3 years instead of 4. So I think the most the Kings can offer in an extension is around 50 mil for 4 years, which won't cut it in my opinion.
I think it will take somewhere around 17/18 mil a year for 4 years to resign him, which I think is fair, but then it's not my money. The Kings can likely resign everyone on the team they want, as long as they're willing to pay the money. Look at the top teams in the league, and you also see the biggest payrolls in the league. What you don't want is to have one of the biggest payrolls and not be competitive.
Personally, I want to keep Bogdanovic, but if it looks like the price is too high, and the right offer comes along, then I'd be on board with trading him. But lets see how he performs this season first. If he can repeat what he did in the world championships, then pay him whatever he wants because you have the makings of an all star. I know everyone is sold on Buddy, but lets be honest. Bogi's biggest problem last season was his shooting. Other than that, he's a better passer and ball handler than Buddy. Buddy is a better rebounder. They could both defend better, but Bogi played and defended 3 different positions.
My point is, if Bogi can shoot the ball this season like he did in the world championships, then there isn't a lot difference between the two of them. Other than a little age
