Should be noted that Tatum missed games at the beginning of the year from injury. He wasn't in basketball shape, took him some time to get into shape, then he got better and better and better.
Culminating in a dominant ACC tournament, a 9 game stretch where he reeled off multiple 20 plus point games, he's three point shot kept improving.
He carried Duke through that stretch. He's got crazy "upside" 6'8" multi level scorers who can do it all. With unbelievable polish at 19 years old don't grow on trees.
