I think Bledsoe is a very good player, but I'm picking Kyrie every time. And it wouldn't be close for me. But you're picking one stat here, and we all know advanced basketball stats aren't as strong as baseball ones. We need a wider picture.
Kyrie had a higher PER, higher TS%, lower TO% (Bledsoe had higher A%). He shoots the 3 better by a lot (40% to 33.5% last year), and in general (47% to 43%). Kyrie's younger by almost 3 years, and has 2 inches on Bledsoe. Kyrie's weakness is defense, but his defensive rating was identical to Bledsoe's last year. In their years in the league (and Bledsoe has had more), Bledsoe has had a VORP of 3 or more once (3.3), and had 2.9 last year. Every other year was sub-2. Irving had a VORP higher than 3 twice (3.7 and 3.3), and just below it twice (2.9 and 2.8). Bledsoe rebounds at a better rate (8 to 5 TRB%), and assists slightly better rate (31.1 to 29.7 AST%).
