Very interesting perspective. I guess each family is different.
Growing up my dad was a high school football couch in Southern California. Football was a family activity and we bonded over it. Every Sunday leading up to the start of the HS season my mom would cook dinner for 40 HS kids and we all hung out at the house after church and watched football talked strategy and bonded. I think the impact on the kids lives to see that football can bring families together was extremely positive. My dad was more of a philosophical coach rather than an Xs and Os guy and so the Sunday discussion was never about Xs and Ox, it was about priorities, life and dedication, but always ended with tossing the football and some critique of skills.
I am not sure I would say that a wife telling a husband to keep football out of the house is something I would think is healthy or not particularly when that is the livelihood of the husband. I know my life would have been completely different without the memories and seeing how hard my dad worked and how much he cared about every kid and also that my mom could see it was so important to him that she made it important to her. I guess it taught me more about life than it did about football.
