At launch for a Monk basically there were a handful of god stats (attack speed, life on hit, dex, all resist, your specific resist, magic find), a handful of ok stats and a large number of garbage stats. Now even a good stat can be worthless because of the large value ranges.
Back of the envelop numbers: say god stats are a 10, ok stats are 4 and dump stats are 2's. Now the MEDIAN item is (roughly) 1% of one with an avg amount of ideal stats (ideal stats with all high end values might be 30 times better).
