With the trading of Pierce and Kg, Ainge didn't want fans to think he was replacing those two because those would be crushing expectations.
Still, with how the average fan was down on this pick I wouldn't mind it if Ainge did some hype for my guy Kelly. For those that like PER as a stat he had the best PER in college, with 30+ rating that is reserved for the likes of Lebron and Durant in the NBA. Obviously he won't be that good but I think he can be a solid starter for the next 10 years.
