To me Brown clearly has the high ceiling. His athleticism is upper echelin in the nba and in that regard he just had the ability to do things that Tatum can't, regardless of his evident skill. It's also worth pointing out that Brown has already demonstrated the ability to improve significantly from years one to year two, that's not a leap that any player including Tatum is guaranteed to make. To me that give the idea of Brown getting even better some credence, because he already done it. In addition for this year it's worth pointing out that Brown typically draws the tougher wing assignment, both offensively and defensively, so this eases Tatum burden. And his shooting from three will regress. Plus I love Jaylen attutude. None of this guarantees Brown will be better, Tatum may be more likely ti reach his ceiling, but I'll take Brown
