Likely one of two things here. Either thats an item Nike sent to Butch when working out to gear packages they were making for UT players. OR, that is just part fo a players only set of gameday gear. typically players have several sets of game day wear and when you are sponsored by Nike you often get Jumpman jumpsuit gear because their Jumpman line makes the highest quality of that stuff, a la, basketball warms ups and things like that.
Or what said above, just a basketball hoodie, lol
