I'm trying to stay away from all the ridiculousness around Brandon Ingram (which hasn't even stopped today), but this is just not accurate. Anyone around Celtics brass would put their defensive pecking order as Brown>>>Smart>>>Tatum. Tatum started off the game on BI but Smart switched to him often. Brown, the Celtics best defender, was on BI the 1st game. Zion started the game with Grant Williams on him. As he often draws the other team's PF, not their best defender.
BI does indeed not only often draw the other team's best defender, but as has been noted, doubles and traps.
We can't be on here talking about how BI rarely draws the other team's best defender, then turn around and complain he doesn't handle doubles and traps well.
