Cover 2 is okay if they are using concepts that try to work both sidelines. It's also good in spots where you don't care if the offense gets completions and just want to force them to throw into the middle to keep the clock running.
Otherwise you are absolutely right: expect to get worked over the middle. Last year the deep half zones and the mid-read could actually do a decent job tightening the window on deep posts. This year it's a one play TD with a simple button press.
