First thing that came to my mind? Commitment. Kawhi's been rockin' the braids since his balls dropped. I dare you to name another NBA player with corn rows that still plays today... and is even remotely relevant. That style was hot back when Iverson and Ben Wallace played but at least they had fancy designs and what not. Kawhi's braids are just so early 2000's and he simply doesn't seem to care.
It works for him though. Kid is making a run at finals MVP. Meanwhile in my middle school ID I had a full blown mustache.
PS- LeBron's actually been sporting the receding hairline look since he was like 3 so props to him on his commitment to the hair game as well.
