That does NOT make him a top 5 offensive player. I don't know how you're parameterizing offensive impact/skillsets, but I can assure you it's not done in that manner. Especially considering that this is Kawhi's first season where he's putting up those type of scoring #s. Players like Curry, Harden, Westbrook, LeBron, AD, Boogie etc etc have done it for longer and on higher volume. And that's before we get into players like Curry, Westbrook, LeBron, CP3, Lowry etc etc who can actually run an elite offense.
When he's been strictly the #1 a/b option in the playoffs he's failed to have any elite impact on offense in any series.
Draymond has been the best defender for two years running, but that's neither here nor there. He won the Finals MVP because he limited the best player in the world while putting up mid-level offensive #s, not because he had an all-time great Finals performance. I don't know why you're using his Finals MVP/ring as if it has any relevance to this discussion, he was never a dominant player at that time.
In no specific order:
KD (top 3)
Curry (top 3)
LeBron (top 3)
AD
Westbrook
Cousins
Kawhi
Harden
Butler
Giannis
A few of those are interchangeable (M.Gasol, Kyrie, Lowry, Wall, PG etc etc to name a few).
