I caught a segment of that Felger and Mazz show. Here's my take. I agree with Felger that its fair to speculate that McDaniels came here with the understanding that he's the heir apparent. It just makes too much sense. What I totally disagreed with him though, was his insistent that if BB isn't retiring after the 2013 season (and I don't think he is), McDaniels is an idiot for not looking into HC'ing jobs now.
McDaniel is just a year + away from a horrible HCing experience, where by all accounts he did a bad job, made a lot of mistakes, and hopefully learned from them. He didn't make it even 2 full years. First I don't think there would be much of a hot market for him, so soon after that debacle. Media speculation, or a casual "what about McDaniels", is one thing. Going after someone is another. He'd be a very hard sell to any fan base after that year and half in Denver.
Secondly, I think he'd be happy to wait 4 or 5 years to succeed BB. Why not? By all accounts he and his family love the NE area. He's well paid, in a great environment, appreciated by the player, coaches and management, and by and large, well liked by the fans. Not a bad gig for the next several years. Plus when the final payoff comes, he get to be the HC of one of the best and most stable franchises in the league. A place where he;ll have the support and infrastructure to compete on a yearly basis, plus by that time his former teammate and best bud will be the GM.
Isn't that worth waiting a few more years, as opposed to rushing into the first HCing job to offer you a job and have to work for a Bill Bidwell, Woody Johnson or the like.
