I think that we have to remember that we are talking about a team that made the finals, may win the whole thing, and has great chemistry and depth. Suns of a year or two ago can swing for the fences. Suns of this year... I don't think it's necessary. They have great chemistry, outstanding depth, and they have a lot of talent. When I look at this team, I see one major hole/ weakness- a tough, athletic PF/ C, assuming they can bring the rotation back for next year. I just don't think that trading three or four rotation players for someone like Siakam is a necessary risk. Wouldn't it be safer to grab an extra big man without giving anything up?
If the Suns finished in the lottery or even got beat in the first round, I'd be in favor of taking a risk, but when you have a team that's going to finish the year as the Western Conference champions (at the very least), I don't think a huge change is needed. If you can get a top-five or even a top-ten player, then maybe, but I don't think I want to destroy the depth and get rid of a lot of potential for someone who is maybe an all-star, and maybe a top 25-30 player in the league.
