Dan Orlovsky about the saints and Kellen Moore

When has a franchise allowed a new coach to lose for 4 years? I am not questioning that we are facing a multi-year rebuild, but coaches don't get a pass to lose for four years.
This is what I said in this thread. Yes, I know I initially said 2 years. For the record, I don't see any coach getting three losing seasons without getting fired.
Does anyone think that will happen in today's NFL?
