The Timberwolves this season is a great example of what happens with a lack of patience with a promising young core. Minnesota had Towns, Wiggins, and Lavine, all born in 1995 with KAT having one less year as a pro.
They traded a 22 year old Lavine after his 3rd year to pair a young core with Butler, won the 8th seed, were eliminated in the 1st round of the playoffs, and Butler wanted out the following season because he felt his teammates didn’t care about winning as much as he did. They traded a 24 year old Wiggins in his 6th season (and the pick that was used to select Kuminga) for a 23 year old D’angelo Russell in his 5th season.
Both players have continued to improve and be integral pieces on better teams, while the Timberwolves flounder tied for 11th in the West.
This isn’t 2k or a game played on paper, young players have to mature into winning players with the rare ATG speeding up the process. Patience!
