ENGLEWOOD, Colo. -- The start of a new Denver Broncos National Football League season is always marked by the buzz of activity.

Whether at the team headquarters, where preparation currently is coupled with a 35 million dollar renovation that will create a state-of-the-art facility for the Broncos, or at the stadium, where team staff and Stadium Management Group employees are feverishly getting the venue ready, things are busy.

Add to the excitement level of the type of team the Broncos have, a defending AFC champion regarded universally as one of the best teams in the NFL, and the electricity level just bounces off the walls.

It is new, but it is new all over again.

We do this every year, and while expectations and hopes are higher than ever, no matter what, it never gets old.

The voice of the San Diego Padres is the great Dick Enberg, who many Bronco fans know well from his many years doing NFL football games on the national networks.

For a time, Dick had retired from broadcasting and was spending most of his time at his San Diego home.

Then, he returned, and once upon a time I was talking to him about why he came back.

He said that while there are parts of any job that are routine, mundane, sometimes tiring, there are also—in certain professions, this being one—electric moments so special that they cannot duplicated any other way.

Dick talked about the smell of the stadium grass when he arrives before the crowds, of sometimes just sitting in his booth or in the bench area as close to alone as can be, and those were some of the reasons he cited.

I would add, for me, I have always loved being at the stadium when the only others present are those who not only "have" to be there, but who choose to be there because that is part of their preparation.

You cannot solve any problem sitting on you couch at home.

Get up, get ready, and go.

I love all the parts of it when it is just me and the game, joined by a few people—coaches, staff members, so like-minded that it adds up to an unspoken fraternity within the playing of the game.

There is a universal truth that I preach all the time:  you are either "in" or you are "out." 

And "in" is measured by a degree that all do not attain. To be frank (and I can be very frank), very few attain this level, although many try to fake it.

But when you are all in, even if one is enjoying a degree of retirement from some of the supposed day to day tasks, you never get tired of seeing it done right.

That means no "t" goes uncrossed and no "i" goes undotted, no matter how much slop you have to crawl through to complete that punctuation.

So here we are, about to embark on a long journey into an uncertain future.

All we have, all we can ever have, is being All In.

It gets age on it, but it never gets old.
