Here's how many of the top 10 players in the last 14 years stayed in their home states (this is to the best of my ability, sorry for errors, rankings per ESPN, prep schools make this challenging)
2007: 3 (Kevin Love, Eric Gordon, Nick Calathes)
2008: 3 (Jrue Holiday, BJ Mullens, JaMychal Green, Demar Derozan)
2009: 2 (Derrick Favors, Kenny Boynton Jr)
2010: 2 (Jared Sullinger, Perry Jones)
2011: 2 (Andre Drummon, Adonis Thomas)
2012: 2 (Isaiah Austin, Cameron Ridley)
2013: 1 (Kasey Hill)
2014: 2 (Myles Turner, Theo Pinson)
2015: 6 (Skal Labissiere, Brandon Ingram, Henry Ellenson, Ivan Rabb, Caleb Swanigan, Malik Newman)
2016: 3 (Harry Giles, Lonzo Ball, Miles Bridges)
2017: 1 (Deandre Ayton $$$$$$)
2018: 2 (Romeo Langford, Jalen Smith)
2019: 4 (James Wiseman $$$, Anthony Edwards, Jaden McDaniels, Nico Mannion)
2020: 3 (Evan Mobley, Greg Brown, Scottie Barnes)
36/140, 25.7% "stayed home". If I have time tomorrow I may look at top 20 and update this post.
So if Minnesota has 4 top 10 kids, in theory, they should get 1. We have had 2 in the past 14 years per ESPN (Tyus was 4, Suggs was 5). Hurt was 11, Tre 17. So landing Chet would put us ahead of average.
