Was it clear? If the guy above you is a freakin moron there isn't much you can do.

What I saw:
WR drops - meh, is that the coach the delivery or crappy WRs?
Bad routes - we already know barbay was garbage, might be a symptom of that more than the we coach
No effort - that's a symptom of the players saying they're done with the system. Yeah he could do a better job getting them to suck it up but...

Is he a good WR coach? I have no idea but I wouldn't judge many position coaches or players based on this years disaster. Effort yes, Tulu can suck it, but execution, I'm not sure you can blame the players or position coaches based on how bad the top was.
