The eye test says Nico runs the offense so much better and has several high IQ plays. Ty creates mismatches, but outside of offensive rebounds, he's not as good as Nico on offense.See all other stats. He's a game manager PG, not a flashy score-first turnover machine that can't guard anyone other than another PG because he's 6'1"
Defenses have not sagged off of him, because when they do he gets inside for an easy two. This is not Jalen Tate.
Of course Ty is light years ahead of him defensively. He's tenacious, athletic, and provides a very unique look for our team. However, he is not the better PG. By your reasoning, Darwin Barney is one of the best second basemen during his time.
