How, pray tell, do the commercials contribute to "the flow of the game"?
Score, 4 min of commercials, kickoff, 4 min of commercials, collinsworth explains that brady/rogers/brees/mahomes is the best in the league (only if they're in the lead) despite claims the week before that one of the others is the best, why their opponent is actually not nearly as terrible as your eyeballs say they are, timeout, 4 min of commercials. Rinse, repeat.
These things do not add to my enjoyment in the least. My brain can process more than one play per real-time minute, and the less jibber-jabber I hear from these talking meatheads, the better. Except Romo. He's delightful to listen to, especially when he tells you what play they'll run next and you can watch it unfold exactly as predicted. I just wish he wasn't paired with Nantz, who is about as interesting as watching paint dry. The NFL needs to get Romo and Al Michaels teamed up. I'd listen to a full 3 hrs of that.
Maybe I've been spoiled by motorsports, which in general takes far fewer breaks, the action rarely stops, and the announcers are more... animated. But even then, I FF through cautions and commercials. As I type this, I'm letting the Daytona 500 get a bit in front of me before I queue it up.
