I guess. I just don't think he would ever find a fit in the NFL. His next job was always going to be a rebuilding job.
Anyway back to Bohl. I still say he is getting to the age that you never know when that last P5 job is going to come. People thought Riley at 60 was too old for Nebraska.
Chip was still a very hot commodity after Philly, regardless of what you and I think of him, he could have had a much better job and still be coaching in his desired league. This is not debatable. Now he's damaged goods, and that isn't debatable either. He screwed up by taking the wrong job. I'm not even saying he would have been successful elsewhere, but he would have had a much better chance and still be coaching in the NFL.
One of the reasons Bohl probably wanted the Minny job is for the money, because as you say he age is starting to work against him and he was running out of chances to sign for great money. Now that he's making 1.4 mil a year at Wyoming, he doesn't have to take a crappy P5 job to get his money. He already has it, something he couldn't say at NDSU.
