What is the most upgradable position on the Wizards?

I've really enjoyed this team so far. Somehow, someway, all four newly acquired Wizards have exceeded my expectations. Kuz is not the Javale McGee second coming I thought he could be. He is a grown man, 3&D and some more microwave scorer. KCP is like Ariza of yester-year, solid 3&d professional with great length. Trez is a monster and a great ambassador for the team. Dinwiddie has a great pace and control of them game, and a smooth shot. Gafford continues to anchor the d and be a lob threat. And Beal is the star scorer. This season has been super fun and I look forward to the rest of the year.

But obviously none of these guys are Durant or Giannis or Steph. And those guys are untouchable. Sitting in the shoes of Tommy, what position, whether by trade or free agent, would you consider most upgradable? What position gets us from good team to contender? Who would you lose? Does someone like Myles Turner, Siakam, Jeremi Grant, Porzingis, or some other fringe all star get us over the top? Do you wait for a potential star to get disgruntled and risk picks and assets (Towns, Ingram, Dame)? Where is the biggest need for an upgrade?

Final disclaimer: it's fun to even be able to ask this question cause I really like this entire squad.
