Two of the stars in tonight's NBA London Game - Ben Simmons of the Philadelphia 76ers and Jayson Tatum of the Boston Celtics - are amongst the leading candidates for the 2018 NBA Rookie of the Year award. At the halfway point of the season, it appears as though the race is a four-way one between these two, Kyle Kuzma of the L.A. Lakers, and Donovan Mitchell  of the Utah Jazz. Even if everything was created equal among those four, there is a 50% chance we are seeing the rookie of the year in out hometown game tonight. But since that is never how it works - how equal are they?
