Bust: Deandre Ayton
Regardless of all the excuses you can make about the team (and its poor management due to its petulant owner), the facts are the facts: the season before DeAndre Ayton arrived in Phoenix, the Suns won 21 games. After Ayton’s first season in the NBA, the Suns won 19 games.
How do you select a player with the #1 overall pick in the NBA Draft, and with virtually the same exact team, end up losing even more games? That should tell you nearly everything you need to know about the impact Ayton has on his team and on winning basketball games in general, no matter what the shiny numbers in his box scores might tell you.
