I'm excited to see the Castle-SGA undercard these next couple games - Castle's been pretty savvy about recognizing how building up your reputation league-wide can influence officiating in your favor and tailoring your game to take advantage of that officiating. His strength-quickness combo is in theory a good counter against SGA if he's allowed to get away with physical defense, and he might have more luck in playing physical than other "non-star" defensive specialists in this department.
Either way, it'll be good for him to get reps in against SGA, who's the king of sucking off refs in public for favorable officiating bias, if for no other reason than to pick up some pointers on using the dark arts
