I believe Jayson Tatum was negatively effected by last season's problems more than any other Celtic. Playing with Irving left him confused about how to play offensively and with badly damaged confidence. Irving's apparent harsh comments to his teammates during games were taken to heart by such a young player with a game based on a high skill level and finesse. I would say he is still playing his way back to form and that it will take awhile, maybe even a season, to rehabilitate his confidence and instinct for the game. Fortunately, this team's best years are in front of it and they have the time to let Tatum find his way back - I would say, then - watch out !!!!
I thought it before the season and I believe it even more now - this group, with a couple of additions and the normal improvement of their young players is looking at multiple titles during the next decade as Kemba and Hayward play at a high level into their 30's and the young stars come into their prime and this crop of rookies grow into important role players that contribute to winning. It's a good time to be a Celtic fan.
