Naah, Smart is in no ways a top 20 player. Top 50, in terms of defensive impact, I could see an argument.
The rankings seem fair overall. What we need to see is a jump in development by Tatum. If he can get into that top 20 conversation, the Celtics could make some noise this season.
If Brown can mature as well then we would have a dynamic duo to go along with Kemba. But we're going to have to wait and see if they can fulfill their promise.
I do NOT want to see Hayward taking away minutes from the young bucks unless he shows he deserves it though. The development of the two jays, like it or not, will likely determine our team's trajectory for the season.
