He didn't quite play all 82 games, though he didn't miss many. While I agree with you that he's a huge defensive talent, I think that his skills are still blossoming and that he's way too young to even have an underrated or overrated label attached.
I have to admit I haven't seen more than a hour or so of him playing in a real game, but he appears to have the speed and instinct to be the kind of hybrid, multi-faceted defender that the new NBA so desperately craves, like a fresh new teenage craze. Everybody wants a Draymond Green, and while I envision Noel to be more of an elite inside defender than Green, his steal stats prove that he's good at poking in thick traffic down in the paint or he's long and quick enough to deflect passes around the perimeter. This is an invaluable asset for a team that strives to run the switch-all defense that Golden State perfected these last couple of years.
I don't really know what his go-to move on offensive is, as I haven't watched him play enough, but ever since draft day he's been heralded as an other-worldly, prodigious defensive talent. He's kind of a smaller center, which is fine when running small ball, which he would fit so nicely into. I wonder what the analytics say about the time of steals Nerlon commonly gets, whether they're on ball, fast-break opportunities or just simply flailing, long arms swiping the ball out of seemingly clear passing lanes. He doesn't seem uncoordinated or obnoxious on, rather the opposite, a slim but muscular physique that doesn't slug behind the guards like the laboring, 250 pound + centers of the distant past.
Marcus Smart has potential, still very young. If he can consistently keep a 35% or higher shooting percentage from the perimeter, you've got yourself a solid SG/PG hybrid that can conveniently defend both positions, switching off to a bigger two-guard or a quicker one-guard confidently and with his signature brand of unique hustle.With his size and mobility, his outside defense would be a high trade asset in a point-guard dominant league. I might be wrong, but I'm sure pretty sure that's why Thomas was a sixth man for a while, because he wasn't able to guard the best scoring points guards we've ever seen. Lucky for him, that off-the-bench season creating a lot of hype for his follow-up season, where his numbers weren't that much more higher and he still struggled balancing being a score-first point guard needing to pass the ball a bit more in Brad Stevens team-dependent style of play.
Add-on: Read an article posted on gm a couple days ago about Marcus Smart that details the same improvements needed that I'd listed, including shooting a higher percentage from the perimeter.

http://basketball.realgm.com/analysis/243198/Marcus-Smart-And-Bostons-Point-Guard-QuestThe article lays out Smarts shooting stats:
"Last season, Smart shot just 21.8 percent on all catch-and-shoot jump shots. In comparison, he shot 39.3 percent on dribble pull-ups."
Most players tend to struggle shooting off the dribble more than a shot in a stand-and-shoot position, where the body is set and prepared. Seeing as Smart is uniquely the opposite, it would seem he has less hill to climb than a stand-and-shoot player, as he's a guard capable of being a shot creator and not typically used as an off-ball outside scorer anyways. It still seems really weird to me that he's more efficient at a dribbling, on-the-move shot than he's on a stand-still jumper. If you watch him play on the court, though, he's not your usual player going through the motions. There's a cleverness to his game, a sneakiness, that makes him unpredictable and energetic on both sides of the floor, but especially while guarding an opponent one-on-one.
Looking at Noel's stats, it seems that either he struggles to gather rebounds or maybe he was playing alongside a packed big-man lineup. He averaged 5.7 rebounds in 30.8 minutes, a pretty horrible statistic that kind of puts a stick on his block-steal numbers. 6 rebounds in 30 minutes? Really? Listed as 6 11' and appearing very agile on the court, one would expect him to bring down at least 9 rebounds. I mean, he's not being given small rookie minutes. He plays for the Sixers. He averaged 30 min per game!!
Hopefully he'll fix a box out or hustle issue and turn into a versatile, dominant defensive/rebounding center. Don't see much hope for his mid-range game improving ,though; his free throw form is absolutely grotesque.
