Jaylen Brown was on a Championship team, but the team around him was one of the best in a long time. Jrue Holliday, Derrick White, Jayson Tatum, a Healthy Kristaps Porzingis and Al Horford. Could have won a Championship with a lot of different players in Jaylen Brown's spot.
Well, when you are not the #1 Option, you arent going to be guarded like the #1 Option. Andre Igoudala was an NBA Finals MVP. But, he certainly wasnt the #1 Option. Jayson Tatum averaged 26.7 ppg that season, Jaylen Brown averaged 23.0 So, he was not the defense's primary focus.
