He played his best when it mattered most. Doncic and Young don't play a lick of D, and haven't taken a team nearly as far as Ayton.
Trae Young lead his team in the Eastern Conference finals with a series lead before he got injured at the same time Ayton helped the Suns get past the Clippers. Trae Young carried Atlanta through a huge postseason run as the man on his team while Ayton anchored our defense. To say he hasn't been nearly as far is just false. If not for Young's injury then I believe the Suns would have met the Hawks in the finals. Trae missed games 4 and 5 before he attempted a return in game 6.
