Same question then about whenever you go from playing Nebraska to the NFL, what was it that, again, was so eye-opening?

Speed, competition, size, what was it?

How much weight did you put on rookie year to the rest of your career?

So you're talking about very small margins.

So even a three-pound difference, you would feel faster or stronger?

Yeah.

You spent over a decade being the captain.

Do you get voted or picked by the coaches to be a captain?

So you played 14 years.

In the last, it feels like the last decade or so, we see a lot more RPOs.

As a linebacker, a lot of that is on you.

Was that something that you had to learn as that started to happen more?

And was that difficult?

Who was the hardest quarterback to have to plan against because of the RPO?

So you're counting on your defensive line to eat up those offensive guys, right?

To give you the, to let you see what's happening and make a decision.

When you win the Super Bowl, I mean, come on, is that the greatest?

Mm-hmm.

Because you're such a buck, a lifelong buck, and you knew it was time to retire.

But is there a little bit of guilt going, man, now they got to replace me?
