Yeah, I expect Smart to take a step back next season without Kyrie here. Smart improved his shot selection in large part due to Kyrie being able to shoulder a lot of the offensive burden for the team.
(1) With Kyrie gone and no PG to replace him and (2) now Horford gone and a serious lack of passing ability throughout the roster ... Smart as the de facto PG = Smart is going to be forced into a lot of situations where he is forced to do more than he is capable of.
Late shot clock situations. Forcing the issue because nobody else can get consistent dribble penetration.
There is a lot of bad shots coming back into Smart's repertoire. His shooting numbers are going to drop off badly next year. He isn't going to be able to maintain his shooting of last season. And his trade value and on court value will both take a hit because of this.
Therefore, I agree that this is the best time to trade Smart. His value will never be higher than it is today.
I also believe Smart is the wrong fit at PG next to Jaylen and Tatum because he doesn't create enough opportunities on offense for himself or others.
And with Jaylen, Tatum and Hayward = opportunities are limited at SG long term for Smart because there is already a serious overload at SF that takes minutes away from where Smart could have a long term future here.
Which means Smart is more of a 6th man backup combo guard long term. Which is good but not a building block.
All in all, I would happily trade Smart to add more viable long term assets. To find someone who fits in better with Jaylen and Tatum. Whether that is a player or a future draft pick.
So yes, I would like to trade Smart too. He is my favourite player on this team and has been since he has got here ... but I do believe now is the time to move him on.
