Lowry was never a scorer to begin with, he scored because there was really no one else then Derozan that could score on that team so he pulled the scoring load a bit to himself because of it.

Now that Derozan is gone but Kawhi and some other role players came in and made raptors a bit better, Lowry can go back to his passing and defensive ways. He is a defense first type of person and pass second so scoring was always his third option. When you have Kawhi on your team you use him to his max and try to keep him happy by giving him the ball as much as he wants so he doesn't leave you next year for Lakers.

Raptors, no matter how much people see them as favorites are not really in the title contention in my eye. Sixers specially with butler addition is much bigger contender. Celtics are amazing on defense but suck sooo much on offense so Sixers can be the deadliest team on the east if Butler doesn't become diva again.
