As expected, Duke's Zion Williamson is No. 1 in my 2019 NBA draft statistical projections. Who's next? Let's update my projections for college prospects who have declared or are automatically eligible for this year's draft.

My statistical projections start by translating NCAA performance to projected NBA rookie performance, also factoring in regression to the mean for outlier performance. I then calculate projected value over the player's first five NBA seasons by combining rookie projections with age. To that stats-only version, I also add a consensus projection that improves predictive power by incorporating where players rank in my colleague Jonathan Givony's top 100 rankings.

I introduced two key adjustments to the projections last year. First, I now incorporate translated performance in the Nike EYBL thanks to statistics compiled by Neil Johnson of ESPN Stats & Information. Second, I'm now adjusting for replacement level by position to account for the surplus of productive big men entering the league.
