Kyrie is the perfect mentor.
Rozier with his length and athleticism,motor and competitive drive is the perfect backup for Kyrie.
Competing daily with Kyrie learning how to use timing, off wrong foot moves ,improving his floater and playing beneath the rim.Dunking on Lebron as makeup for being blocked-more like being aware of who was coming and countering that,being a step ahead upstairs.
Why leave to become a incomplete point guard that will have a lower ceiling.
Rozier has relied on athleticism and burst but Kyrie is the true prodigy ,i believe Rozier has the tools,drive,defense but can learn much more in Boston surrounded with Tatum and Brown.
If Rozier leaves he will not reach the potential of playing with Kyrie and Gordon under Brad Stevens.
There is so much to being a true point guard he is only 23.
