Kanter as a PF on offense would be unstopable. He is too strong, has the size and way too many moves in the post with a great touch and range on his jumper. He has the footwork and quickness, too. He will get many offensive rebounds (3-4 per game) which means many second scoring options. If he drives more to the basket (which he really can) there will be around 5 free throws for him per game. He has all the skills on offense which should make him one of the most dominant offensive big man in the league in the years to come. He will be our Go-to-Guy. Don't forget he is still very raw and has shown only some glimpses of what he can become. He is also a great free throw shooter, making 80 percent from behind the line.
Hayward looks like the second or third scoring option that rather wants to distribute the ball and having impact on many other areas. I see him struggle more against elite level wing defenders and I don't think that he will be enough consisstent to be the best scorer.
Again, unless Hayward gets more minutes, Kanter will be our first scoring option. Fact is that Corbin will play Hayward more and that's why I think Hayward is the answer.
