No. 5 Going all-in too soon
Patience is key to building a championship contender. Many players will not be ready to win and start making the playoffs for four to five years at the beginning of their careers. Tearing apart potential room for growth by going all-in too quickly is a recipe for disaster.
All too often, teams looking to make the playoffs with a decent young core go and sign complementary pieces to help their players make the postseason. This is all fine and well, unless the young core isn’t quite there yet and it lands you right into the land of the forgotten. An area Wizards fans know all too well.
The Dallas Mavericks made this mistake by adding Kristaps Porzingis and Tim Hardaway Jr to the roster next to Luka Doncic. This pushed them into the postseason, but they still weren’t good enough to become a strong title favorite.
None of these mistakes are mutually exclusive and teams often times make multiple mistakes in the same rebuild. If the Washington Wizards truly want to win championships, they will need to be patient and wait for opportunities to grow.
