The first premise is garbage, it starts with an absolute. Offense only players always being divisive. That's false. Reggie Miller was divisive? Ray Allen was divisive? Tracy McGrady was divisive? Dennis Scott was divisive? Allen Houston was divisive?
And as far as score-first point guards being a particularly distrusted archetype, that depends on their skill level relative to the rest of the team, and their ability to function within a winning culture. Tony Parker existed for years as the second or third option within a winning culture deferring to superior offensive players until it was his turn. Whereas Russell Westbrook could not defer adequately to a superior offensive player in Durant.
Both (Parker/Irving) are scoring PGs, but their talents differ. I'd even say that Irving is on an entirely different level at this age range, and projects to be the far better player lifetime. One is a far superior Iso player, whereas the other does most damage with the assistance of a pick and roll situation. One is a career abysmal shooter from 3, whereas the other routinely shoots between 35%-40% (aside from one year). One is an excellent FT shooter, the other took a while to arrive at good. One has to get into a particular range to be consistently effective, whereas the other can get the job done from anywhere. So while they have a similar label, they play differently, and one is in a different realm talent-wise.
Historically, the PG's primary role is ball distribution. In an ever evolving game, fans are starting to grasp with the reality that this is no longer a necessity. Especially, when the role is being provided for elsewhere in the lineup. And that's why I am of the opinion that all scoring point guards (or undersized SG's, which often are the same thing) need to be coupled with tall, lengthy, fairly defensive minded, ball distributive, court-stretching combo guard/SF's.
The primary aggravation with Parker is with his declining ability, and his skillset in this changed format in terms of offensive hierarchy. Evidenced by Patty's more natural fit as a pure shooter with the SL core offensive centerpieces, comparatively to Parker (Although he has improved his long distance shooting). Irving being a pure scorer is a necessity with Cleveland whether it was pre-Bron or with Bron. As is a obvious lack of pure scoring on that roster, especially in regards to shot creation outside of LBJ on an elite level. Love was downright laughable at times.
