Aha, an intelligently thought out rationale for what kind of person would make a good coach, but acknowledging that individual might not be a well-known guy who's high on the radar yet? Holy shit, there is hope for the who-would-replace-Tomlin dilemma.
Seriously though, I think that is a pretty damn accurate list of what they need to be looking for. I do think there is a better chance that Rudolph (assuming our optimism is well-founded) would do all right in a Ben-themed offense than Ben would do well in a precision spread attack. Ben is kind of his own animal, and what works with him is gonna work and what's not is just not at this point, so why fight it. I do think that a big reason why Tomlin has been so insulated from the true "hot seat" thus far is the not wanting to switch head coaches so late in your franchise QB's career. BUT ... it really seems like either one of those dominoes could fall at any time, though.
One other thing that's not talked about very much - Colbert is something like 62 or 63 years old, and his contract runs out after this year (
team didn't renew it). If he resigns / retires / is fired / mutually parts ways / whatever - that could be the catalyst for a lot of changes to happen in a hurry. A new guy comes in and says, "I have a plan, I see the pieces I've got and I want to do X with them," well then that could set up #3-4-5 on your list pretty quick. Assuming the GM knows what he's doing. No one would be sacred in that case, not even Ben.
Basically, any one of three things -- Ben retiring, Tomlin fired, Colbert retiring -- which are all growing increasingly likely with each passing year, stands a good chance of triggering the other two. I'd say it's better than 50-50 it happens this year or next. I should add that Tomlin being fired is the least likely to happen first.
