I find it interesting that so many people talk as though we have had good play making guards up until now. Consider the assist to turnover ratios from the last few years (ordered by minutes)
2013-4 Bledsoe 1.7, Dragic 2.1, Barbosa 1.7, Ish Smith 2.9 and we didn't keep him
2014-5 Bledsoe 1.8, Knight 1.8
2015-6 Bledsoe 1.7, Knight 1.5 (Booker 1.3)
2016-7 Bledsoe 1.9, Knight 1.5, Ulis 2.9 (Booker 1.1)
2017-8 Payton 2.3, Ulis 2.4, Canaan 2.6, Harrison 2.5 (Booker 1.3)
I added Booker just in case you were wondering. The league average for all PGs was 2.4 this last season so our PGs in recent times have been well below average as playmakers. Canaan and Harrison promise to be a breath of fresh air.
I don't believe anyone thinks we had good playmaking prior to this year but we at least had PG's who belonged in the NBA. They may have been average or below average playmakers but they were capable of scoring 20+ points a game and playing average to good defense. They also required someone guard them when they were within 25 feet of the basket. If you don't see past the stats and see why having Bledsoe, Dragic, IT, and Knight was better than Harrison, Canaan, and Okobo then you're just not viewing the whole picture.
Everyone admits we've been bad the last few years. Downgrading the PG position when we finally upgrade every other position is not the way to improve our future. The Suns need to improve quite a bit to become a playoff team and while we won't be this year we should win 10 more games than we did last season. The years of 50+ losses are hopefully over. We have a lot more talent on the roster now, not just starting but also in our 2nd unit, at every position but PG where we went from having borderline All-Stars like Bledsoe and Dragic to 2 guys who weren't even G-League All-Stars in Harrison and Canaan.
