I'd grade him a B+. Guys were going nuts and screaming in the forums about the pick, but he put up a promising year as an ok backup (starter even) on a playoff team that went to the conference finals and won 50+ games. Btw LA TP for owning up, I'm still looking for Clench and CoachBo.
As for expectations I expect him to improve to numbers like 13 PPG, 5 RPG and 3 APG in ~24 minutes per game. But hey I'm always hoping for him to become the next MJ 
TP for the being the first to post in the thread. We need to get you to triple digits

.
As for your expectations/projections for next year, the rebounding and passing categories are the ones about which I'm most concerned. While I have seen him make a few good/great passes, as well as make better decisions on the break than any of our guards (which is beyond pathetic, to me), the guy had stretches of 2, 3, and even 5 games in a row without recording an assist

. How is that even possible, lol

? Clearly he's been spending too much time with Avery Bradley (sarcasm). Granted, I wasn't exactly expecting him to be Rondo or anything, but I find it alarming that, despite averaging 17.2 mpg, he didn't even register 1 assist per contest

.
Additionally, if there's one thing this team desperately needs, it's rebounding, and again, I wasn't looking for him to be, well, even Rondo

, on the boards, but you're telling me that with his athletic gifts and physical tools that he couldn't grab 10 rebounds in a single game? Not one? Case in point, in two starts against the Raptors in February he grabbed a total of...one offensive rebound, while also posting a combined...two assists? Seriously?
Even in the playoffs, during game 4 against Cleveland, he played 20 minutes and yet somehow failed to corral a single rebound or record even one assist or steal. Wat

.
I guess what I'm trying to get at, here, is that he seems pretty limited as far as contributing to winning. Like, if he isn't scoring, what else does he offer, which was one of the primary reasons why I liked, and still do like, Kris Dunn over him, because even if he doesn't score, Dunn will stuff the stat sheet, so to speak, and you know he's out there. With Brown it's like, well, I guess it's easy to see that he's a Kobe fan, lol

. Ugh.
