How to tell if script/asset is loaded by Asynchronous or Deferred in Chrome Network Tools
Unfortunately, you can't see dependencies in the critical rendering path in the network tab of Google Chrome.
What you can do is look at the priority of requests (you might have to enable this tab in the network windows -> right click on the tabs). An async request should have a low priority (just like images which are loaded async). Chromes appears to do just that (https://bugs.chromium.org/p/chromium/issues/detail?id=408229), it's not super accurate, but might help you.
