I think he will be alright as long as he isn't the focal point of your offense. There's just no way you can give him a high amount of touches, he'd be fine as a 3rd, preferably 4th option. Unfortunately he'll get paid like a 1st option.
I don't mind watching the Pacers, but Atlanta has to be the most annoying team to be a fan of in the NBA. They've had the same goddamn team for like a decade now, have never been serious contenders during that time, and Josh Smith repeatedly refuses to even try to do the things that could theoretically make him really good.
