Dolphins interview Kris Richard for DC Job

You think the reason is because DA could not "man up" or that DA's defense has performed so well over the years that his assistants are being looked at for Coordinator positions? Everything can not be a shot against DA, if we hired a new OC is it because his other job the coach couldn't "man up" and give him a OC position or a testament to how productive that unit was under that coach?
Nope, everything is his fault. Shoot, it took half a season for the defense to get right.
