i actually think this is a fair question, i was legit puzzled myself as to why jay said that
the only thing i could point to that remotely came off soft was biggie being shook to engage with tupac in battle. pac shyt all over him and you heard barely a whisper from biggie, that is until he jokes about pac fukking his wife on brooklyn's finest. then he drops sublims on long kiss goodnight after the man passes away, lame.
but that was really one man's beef with another as opposed to being about my city as a whole. so i dunno man
