Are the Warriors underrated?

The reason you think they are underrated is because of their offense. They have a top five offensive team in the NBA. The problem with the Warriors is that they can't stop other teams. You mentioned two good defenders for the Warriors, but they don't execute. Don Nelson is an offensive coach, making the Warriors an offensive team. Defense wins championships, something the Warriors don't. And also with the Warriors offense anyone could grab good stats. The Warriors bring the most D-League players into the NBA each year, with far more players from the D-League than any other team. It's not necessarily that these guys are great. The players are decent, and in a system like this, anyone can score. That's why Warriors players are so popular for fantasy basketball.
