Why is that? I mean you can make a case for Ayton > Doncic in a vacuum (though I would disagree) but for the Kings specifically I dont see it. In my opinion, the Kings starve for high IQ wing players that can shoot, pass and playmake. The last thing they need positionally is another young Center that likes to have the ball in the post and doesnt protect the rim. There are already four of those on the team.
Because I have no trust in the big man on this team being main bigs on a perennial contender. WCS shows flashes but I am not convinced that he is your main big on a very good team because he just doesn't rebound enough for a main big. I love his length, athleticism and developing offensive game but he falls short on KEY elements (IMHO) for a big man which are rebounding, defense and ability to have the go to scoring move.
Maybe Giles can be that guy but from what I have seen so far from our bigs, there is not a single player there that I would be comfortable with them being the number #1 big on a perennial contender. With wings, these are easier to get than quality big men. I love Doncic. I think he is the best young European prospect I have seen in my lifetime, at least in terms of production. However, I would be a bit concerned with our wing athleticism. Bogdan, Luka and Buddy are not exactly athletically gifted and in a league that relies on a lot of perimeter scorers, that could spell trouble defensively. Also you have Fox and Bogdan who are at their best when they create. Add Luka to that mix and you have 3 players that are most effective when they run the show.
With Ayton, I love the size and the offensive potential. He is an elite rebounder, can score in the low post and has a jumper that will develop and stretch our to 3pt line. I am a bit old school but I believe that the two most difficult positions to fill are C and PG. If you get Ayton, there is your go to scorer in time. Both Ayton and Fox will develop those jumpers which will improve with the spacing when the Kings are ready to contend.
You have Bogdan at SG who can play off the ball or create and is a decent defender. Next to Ayton, you can have WCS but ideally you want someone who is a better rebounder, defender and can stretch the floor. Maybe Giles, or maybe Skal if he ever develops. Then at SF you can really get a way with a high level role playing SF a 3 and D type of guy. With Ayton being a great rebounder, you can afford to play small ball around him without really losing the battle of the boards. When you have a big guy that can control the boards it opens up a number of options and different looks you can throw at the opposition.
I would be happy with either Doncic or Ayton but if I was building the team, I would want a big guy to pair with Fox. They might appear as not a great fit at the moment, but I am looking 2-3 years from now when both get their jumpers to the point where they can stretch the floor which improves the spacing. Maybe I am wrong, it won't be the first time. Maybe Giles is really that good that we have our franchise big but I haven't seen him play at NBA level so I can't make that call. All I can go on is what I have see on the court.
