I know what you mean but I'm not worried. That's a concern for the teams who pay big money to vaguely top-10ish QBs. For elite QBs the Super Bowl window is the length of their career.
The NFL just got fortunate that there were genuinely 7 worthy AFC teams this year. If there's a different year where both the AFC and NFC only have 4-5 good teams, the 7 teams playoffs will be unbearable.
The constant reviews on big plays just suck. I'm sorry but I'll take some wrong calls for quicker games with better entertainment value, especially considering they often don't get it right even after the review.
