It's going to happen, once Coach Day and Co shove a boot up Harbaugh and friends butts this year, Harbaugh will be gone, he will behind the scenes be fired but in public it will be moving on to another job in the NFL, or he will "retire".
Anyways, what coach do you not want them to go after, and who do you want them to go after.
Me personally, I hope they keep Harbaugh forever, if they think he is the saviour, with his outdated offense, we will never lose to them.
