I love Smart and his defense and overall hustle, but I have to go with Rozier here. I think he just has a higher ceiling, and will keep improving offensively and defensively every year. The guy is just so athletic, he gets to the rim pretty easily just has trouble finishing, and it looks like he's go an extra gear on defense (versatile on defense too). I very possibly could be too high on Rozier, but I think someday he might become more than just a role-player.
Definitely close though, they're both going to be important players for us in on way or another, I hope we keep em. Smart, Rozier, Brown + our pick is a solid young core that's helping us now, getting experience and that will make us legit for years and years.
