Rather than ride a shuttle to Boiseโ€™s Taco Bell Arena last week, I walked a mile or two on Broadway Avenue until I reached Albertsons Stadium. Itโ€™s the place with the blue turf.

The stadium itself is nothing stupefying; it is smaller, 36,387 capacity, than every football stadium in the Pac-12 except the one at Washington State. Itโ€™s not even a tough ticket any more: Average attendance at Albertsons Stadium last year was a trifling 31,126.

Nothing to see here folks, move along.

But as I neared Bronco Lane, I saw a statue of a man, obviously the likeness an old Boise State football coach. It wasnโ€™t any of the Broncosโ€™ coaches you may have seen guiding bowl game upsets over Oklahoma, TCU and Arizona; not Dan Hawkins or Dirk Koetter or Chris Petersen.

It was Lyle Smith, who coached the Broncos from 1947-67, and was then their athletic director until 1981. Smith was a man of such stature in Boise that the famous blue turf โ€” Lyle Smith Field โ€” bears his name.

If anyone in Boise speaks of the โ€œSmith era,โ€ they arenโ€™t exaggerating or using the wrong term.

Smith oversaw the Broncosโ€™ football operation for 34 years, taking it from a junior college national championship to a Division I-AA national championship.

Thatโ€™s an era. Thatโ€™s why you build a statue of a coach.

No football coach at Arizona has ever had an โ€œera.โ€ Not in the truest sense of the word. Pop McKale coached the Wildcats for 16 years, but he averaged five victories a year.

Dick Tomey coached Arizona for 14 seasons. Was that really an โ€œera?โ€ There was no Rose Bowl. The school requested he leave two years after the best season in school history. You would never willingly end an โ€œeraโ€ if it was truly treasured, would you?

โ€œEraโ€ is a word too loosely tossed around in sports.

I bring this to your attention because Kevin Sumlin staged his first spring practice at Arizona on Monday. I checked the Twitter feeds connected to the school and many of them said:

โ€œThe new era starts now.โ€

Itโ€™s not a new era at all. Perhaps itโ€™s โ€œa new chapter.โ€ Or โ€œa day of new faces.โ€

College football has become such a transient industry โ€” moving parts and moving people โ€” that few head coaches stay around long enough to have an โ€œeraโ€ any more. Few stay around long enough to become โ€œold faces.โ€

Terry Donahue had an โ€œeraโ€ at UCLA, from 1976-95. He coached the Bruins in four Rose Bowls.

Pete Carroll at USC? He was gone in eight years. Thatโ€™s not an โ€œera.โ€ Thatโ€™s a โ€œtermโ€ or a โ€œstint.โ€

If the school builds a statue of an old coach, you can consider it an โ€œera.โ€ USC erected a statue of John McKay, not Pete Carroll. McKay coached the Trojans from 1960-75 and coached in eight Rose Bowls. You can see the John McKay statue outside USCโ€™s Heritage Hall.

Rich Rodriguez did not enjoy an โ€œeraโ€ at West Virginia or anywhere. His longest period of employment was seven years, at West Virginia.

People may wish to refer to RichRodโ€™s UA term as the โ€œRichRod yearsโ€ much the same way as they discuss the โ€œMackovic years.โ€ Two terms with unhappy endings.

Once you leave your old school, you are forgotten with haste.

After going 12-1 at Houston in 2011, Sumlin was hired by nearby Texas A&M and the Aggies advertised it as the โ€œSumlin Era.โ€

After six seasons, which included a 25-23 record in the SEC, the Aggies paid Sumlin a fortune to go away, and awarded Florida Stateโ€™s Jimbo Fisher $75 million to start a new โ€œera.โ€

The Aggies opened spring practice Tuesday, and it was as if Sumlin never existed.

Fisher told reporters how A&Mโ€™s new strength and conditioning coach, Jerry Schmidt, has altered the physical dimensions of the Aggies in just three months.

โ€œThe bodies have changed,โ€ Fisher said. โ€œWeโ€™ve changed a lot of the fat and put up a lot of muscle. Theyโ€™ve done a good job of working in the offseason. I mean, their attitude, demeanor, that type of stuff Iโ€™ve been extremely pleased with.โ€

Sumlin has only been gone for 3ยฝ months, yet everything changed at Texas A&M. Names. Faces. Bodies.

Sumlin, too, hired a new strength and conditioning coach at Arizona: Brian Johnson. That transaction embodies the new age of college football. Over the last seven years, Johnson has worked on changing bodies at Texas A&M, LSU, Akron, Florida State and for the San Francisco 49ers.

Thatโ€™s a lot of change in a small period of time, but it fits the Pac-12, which has five new head coaches working spring practice this month. Thatโ€™s college football.

The Kevin Sumlin days have begun at Arizona. If he is still on the job in 2035, you may wish to reserve time for a statue dedication in his honor. Thatโ€™d be an era unlike any in UA football history.

Otherwise, itโ€™s Chapter 1: The Work Begins.
