This team lacks leadership. It lacks a true alpha.
When the supposed leader of the team is a self centered player. The rest of the team follows suit.
Tatum is immature at this point, maybe he grows into the role, probably not. To me he was anointed and didnt work on game to get there. He is the same player as he was when he came into the league (skills wise). In a sense he is worse, because now he chucks up 25 shots a game no matter what. He is an entitled player, those types usually do not win, especially early in their careers.
Much of this is Stevens' fault where he deferred to his players and let them shoot regardless. That is why Smart has his awful nights.
They dont have a point guard, Smart is overrated by the Celtix faithful. He is a defensive sparkplug, he should not be starting or ever taking more then 10 shots a game unless he made 6 of those first 9.
Until those 2 players start involving their teammates, this team as constructed is going nowhere.
