Why didn't the NBA see Jalen Brunson coming?

Dan Devine, cohost of The Big Number and senior NBA writer for Yahoo, joins Ryan Nanni to discuss the persistent narrative of Jalen Brunson, The Most Unexpected Finals MVP. What makes Brunson different from other small guards before him? Why did the league seemingly undervalue a player who'd won so consistently in high school and college? And what might teams learn from watching Brunson lead the Knicks to a titlle? Phantom Island is presented by Homefield and produced by Michael Surber.
