Rajon Rondo is known as kind of a weird dude. He has a weird game, being a ridiculously athletic and intelligent passer with no reliable jump shot to speak of. He has kind of a weirdly shaped head, if you really look at it. And, well, his pregame meal choice is pretty weird, too, you guys.
Yup, that's Gatorade and sushi right there. No big deal, just mixing traditional Japanese cuisine with a sports drink that has like a gajillion grams of sugar in it. They go together like lamb and tuna fish.
