Well, many religions require people to follow a defined path and ask limited number of questions. In that sort of world someone like Mike can not only be adequate, but possibly strive. I could see him as an extremely passionate pastor who if you've already bought into the message he's providing a level of energy that's refreshing and appreciated.
Reggie White (RIP) was similar. When he spoke in the church people loved him. Sometimes he'd step over the line when it came to racial stereotypes or homosexuality, but within those walls he was given that latitude to preach his way.
Specifically to the "forced to follow" part most people don't make objective decisions to join a specific following. Their family/network was a specific religion and went to a specific church, so they did the same. It's not like they take some time, look at all religions and pick one that feels like it's for them. Often in that world the actual person delivering the message from God can be kinda boring.
I don't mean this as a knock on organized religion or Singletary himself. I think everyone has recognized that he not a good coaching fit for this era. But, I do think he'd find a fulfilling next career within the church and I also think they would appreciate someone that has his level of energy and cache.
