2 completely different players/people/roles/etc etc et alia. And ‘reports’ said his strong goal was to remain in La La Land.
I'd have gone with Rui and not resigned Tari - or done a S&T with Tari to get an asset in return. Smart wouldn't have been on my radar, dude sucks at shooting and is just another of those Ime guys. I'd have made Grimes my priority at guard.
Smart on his salary is better than Rui on his salary. Not sure I would have done either. I would worry about Smart's age and Rui's reliance on LeBron, Reeves, and Luka for wide open looks.
Smart's contract and what he brings....those alone, are more than enough justification. But, his presence allows for FVV and his expiring getting dealt.
