If Tatum continues at this rate I think he will close this out as the series leader in Points, rebounds and assists. He already leads the series in rebounds and assists, and is only 0.5 RPG behind Bam for the rebounding lead.
He's actually one of only 3 players in the playoffs averaging 20+ points, 10+ rebounds and 6+ assists (the others being Embiid and Jokic).
