Interesting parallel to Brady, who also tore his ACL at 30 or 31 years old. At that time, Brady had been to 4 Super Bowls with a record of 3-1; Mahomes has been to 5 with a record of 3-2. However, Brady was coming off of a perfect regular season; Mahomes was finishing up a game in which his team was eliminated from playoff contention with 3 games left.
So, while these guys will have experienced this injury at almost the exact same point in their careers and have accomplished similar success to that point, their teams were/are heading in very different directions.
Also of note is that the injury will theoretically impact Mahomes significantly more than it did Brady. Brady as we know was a pure pocket passer. Mahomes is still very reliant on escaping the pocket and extending plays. He will struggle to do that on a reconstructed ACL for a while, and even when he’s fully recovered (2027?), his mobility will not be what it was. Plus, he will just be older by then - 32+ years old - would have been naturally slowing down anyway. So he will need to start transitioning to mainly being a pocket passer now, and I don’t think he will be nearly as successful at it. At least, he won’t be Brady-level “second dynasty in my late 30s” successful.
Their defense is aging, their OL still isn’t that good overall, Kelce is going to retire, they have one consistently good receiver in Rice who has off-field issues. Things not looking up in KC.
