Sprinter Trayvon Bromell spends countless hours watching film. He rewinds and slows down his 100-meter races and practice sessions. He analyzes his form and figures out what he can do better. He also takes a good look at the greats in his sport. Carl Lewis, Maurice Greene, Justin Gatlin, Tyson Gay, Usain Bolt. He wants to learn from the best because, as he often tells his coach, he wants “to be the best sprinter ever.’’

For most 20-year-olds, those words wouldn’t be taken seriously. But Bromell is more than a big-talking athlete. He is a precocious talent who won bronze in the 100 meters at the 2015 world championships. Then, last October, he gave up the remainder of his NCAA eligibility at Baylor University, turned professional, and signed a multiyear endorsement contract with New Balance.

“It happened kind of fast,’’ said Bromell of his transition from college to professional sprinter. “I wasn’t really thinking about it until I got the third-place position at Worlds. Then, opportunity came.’’

And with the Olympics ahead, the opportunity couldn’t have come at a better time. Hoping to build on his success at the World Championships, Bromell’s training and racing is geared toward a strong performance at the US Olympic Trials in July and a trip to the Rio in August. If all goes very well, he could be an Olympic medalist and one of the breakout stars on the US team. Yet, none of that fazes him.

“With this being my first year as a professional, I’m not feeling any pressure,’’ said Bromell, who will compete in the 60-meter dash at the New Balance Indoor Grand Prix on Sunday at the Reggie Lewis Center. “It’s like when you go into your freshman year of college. You don’t really have any expectations. It’s all about let’s see what you can do. So, I’m just going to have fun, to run and see where I place. It’s not about I’ve got to win. It’s a new beginning.’’

While it may be a new beginning, Bromell and coach Michael Ford have kept the sprinter’s daily routine and competition schedule largely unchanged from his time as a student-athlete. After all, it worked exceptionally well during Bromell’s freshman and sophomore years.

During his time competing for Baylor, Bromell recorded the 10 fastest 100-meter times in school history and set school records at 200 meters and 60 meters indoors. As a freshman, on his way to the 100-meter title at the NCAA outdoor championships, Bromell established a junior world record of 9.97 seconds. Last June, he ran a personal best of 9.84 seconds in the 100 at the 2015 US championships.

These days, Bromell still attends class from 8 a.m. until 2 p.m., then he heads to track practice. And he still races indoors like he did in college.

“It is a job so it is a little more serious,’’ said Bromell. “But I feel like when you take things too seriously, that’s when stuff starts going wrong. So, I try to keep it same.’’

Added Ford: “I’ve seen a lot of young sprinters turn pro and decide not to do indoor. Then they struggle outdoor and the season becomes make or break and they think about that.’’

Ford first saw Bromell in a video from the sprinter’s high school days in St. Petersburg, Fla., before Bromell became the first US high school sprinter to break the 10-second barrier in the 100. Ford liked Bromell’s fluid stride and thought, “When he gets stronger, he’s going to be pretty good.’’ So Ford, who is also the Baylor associate track coach, recruited Bromell.

But while Ford spotted Bromell’s promise relatively early, he had no idea the sprinter would rise as quickly through the national and international ranks as he has. Now, in addition to working with Bromell on getting stronger and leaving the blocks with greater efficiency, Ford helps prepare Bromell for the mental challenges that come with a sprinting career.

“Every meet we go to, from the small meets to the bigger meets to the world championships, we’re always talking about being the best Trayvon Bromell,’’ said Ford. “We’re not really worrying about the competition, just racing the clock. We try to keep it simple.’’

That also describes how Bromell handles life away from the track.

“If I’m not training, I’m sleeping or recovering because I’ve got to get ready for the next day,’’ said Bromell. “I always take care of my body.’’

After the indoor season, Bromell’s outdoor track schedule will take shape. Ford raised the possibility of Bromell running both the 100 and 200 at the US Olympic trials. Ford believes Bromell can be “world class’’ in both events. And after his world championships experience, Bromell believes he can compete with the sport’s biggest names on the biggest stages.

“It was a humbling experience to run against those guys — Bolt, Gatlin, Gay,’’ said Bromell. “But I look at them as any other person. We’re all out there running and having fun with what we do, and I feel like anybody can be beaten any given day.’’
