Both Derozan and the Raptors are playing at a level that we have not seen before. Could they regress? Sure, but right now this kind of performance is unparalleled in their respective histories. Demar is more efficient than ever, he's not shy about the occasional three, and he's a very willing passer. The team on the other hand, like NJH points out, has talent all over. The second unit might have the best defense in the NBA, and they absolutely ADORE ball movement, even if for the most part they're not offensively polished enough to make shots.
Obviously this means s*** if we get to the playoffs and we get demolished by LeBron and co. again, but at the very least this looks like a noticeably better team, hopefully they won't disappoint. Basketball in Toronto is really fun at the moment.
