Don't take my word for it. Take the word of everyone from Pops to Duncan to the commentators, to...well you get the idea. The guy is headed for the Paul George level (not Lebron or Durant level). Next year will be an interesting season for him as people will expect the Leonard from the Finals, only year round. Should be fun to see how he does.
That said, Austin Rivers is coming up on his 3rd year. Let's hope he makes that Leonard type jump.
