I don’t think Brad is the problem, per se. But I do recall Larry Bird saying something to the effect of players need to hear a new voice every 4-5 years, and this year it feels like there’s some truth to that.
So the solution, according to Bird, would be to change the players or change the coach. And I think given that’s it’s unlikely we’ll find another Tatum and Brown via trade, changing Brad is the option that is recommended.
