You really do change goalpost a lot. Curry's not a bad defender. He used to be more of a reliability early on, but as of the last few years he's been pretty good. You should look at his defensive ratings during these playoffs. Speaking of Shaq, do you know who his favorite player during the modern era??
Actually, the only people that look foolish are the ones that think Curry is a top ten player of all time which he clearly isn't if you look at the whole picture and aren't a prisoner of the moment.
