In my interview with Brian Scalabrine prior to this season, he was absolutely bullish on the Jay-Team, Jaylen Brown and Jayson Tatum. He told me that a young age, he looks at body and mentality. He stressed their mentality, stating "...both of those guys have a great head on their shoulders - not good, it's great!" Those "great heads" are still there but may need some adjustment.
Let's face it. Jaylen and Jayson were stars in the Celtics playoff run last season.
