How many finals in a row would Luka make if he spent his prime in 2003-2018 LEast?

[superduper]

And would he need to collude to multiple superteams to do it?

Considering the most your hero Jordan ever made was in the EAST was three consecutive Finals before claiming mental exhaustion, thereby starting his retirement tour early I'd suggest being awfully careful with what you're asking. Jordan could only muster three consecutive at his peak. Would Luka make 4 and best your hero? Stay tuned.
