RIO DE JANEIRO (AP) " Carolina Panthers wide receiver Ted Ginn Jr. has a unique perspective on Usain Bolt, who further burnished his credentials at the Rio Olympics as the greatest sprinter in history.
Ginn competed against the Jamaican when their 4x100-meter relay teams squared off in high school at the prestigious Penn Relays.
He was recruited to Ohio State with the thought that he could qualify for the 2008 Olympics, and he ran the 100 meters in 10.2 seconds as a freshman. Ginn chose football over track, and now is gearing up for another season with the Panthers after coming up short in the last Super Bowl.
"Just watching (the Olympics) on TV right now, I kind of get goosebumps on certain races ... like the 4x400, the 400, 200, 110," Ginn told reporters during training camp. "That gives me goosebumps, because a lot of them guys are No. 1 guys we raced in high school."
Ginn is one of several NFL players who had stellar track careers before football " a sport where Olympic speed is a coveted commodity. Many of them were so good at sprints, jumps and hurdles in college or high school that they thought long and hard about pursuing Olympic gold over a Super Bowl ring.
Here is a look at some of them:
MARQUISE GOODWIN: The Buffalo Bills wideout attempted last month to qualify for the Rio Games in long jump, but finished seventh, blaming the result on a strained hamstring from the qualifications. He made the Olympic track and field team in London in 2012, finishing 10th in long jump. Goodwin, a two-time NCAA champion in the event, is now with the Bills getting ready for the 2016 season.
JAMAAL CHARLES: Before he became one of the top running backs in football, Charles was an elite sprinter. His best time in the 100 in college at the University of Texas was 10.27. By comparison, Bolt clocked in at 9.81 in his gold medal win in Rio.
During the NFL lockout a few years ago, Charles told The Associated Press that he would have gone back to track if the work stoppage dragged into the season. "Track is my first love," he said.
CHRIS JOHNSON: While a running back for the Tennessee Titans, Johnson raised eyebrows during the 2012 London Games when he told the Tennessean he could beat Bolt in the 40-yard dash. Johnson had good reason to be confident about his chances in the 40. Bolt is a slow starter, and Johnson holds the record for fastest time in the 40-yard dash at the NFL combine " 4.24 seconds.
ROBERT GRIFFIN III: The Cleveland Browns quarterback was a superb hurdler at Baylor University before he made football his focus and became a Heisman Trophy winner. He was an All-American in the 400-meter hurdles, with a career-best time of 49.22 to win the Big 12 Outdoor Championship in 2008. The gold medalist in the event Thursday finished in 47.73.
ADRIAN PETERSON: The Minnesota Vikings running back was a high school track star in Palestine, Texas, before playing football at Oklahoma. He ran personal bests of 10.19 seconds in the 100 and 21.23 seconds in the 200. While he was in a contract dispute with the Vikings two years ago, Peterson briefly considered leaving the NFL to make a run at the Olympics.
PAST GENERATION: Former Detroit Lions running back Jahvid Best qualified for the Rio Olympics for his father's native St. Lucia and ran against Bolt in Rio in a preliminary race in the 100. He did not advance after finishing in 10.16.
The former NFL players who had perhaps the most decorated track careers were Bob Hayes and Renaldo Nehemiah. Nicknamed "Bullet," Hayes won two gold medals in the 1964 Olympics with electrifying performances in the 100 (10 seconds) and 4x100 relay. He went on to become an All-Pro and Super Bowl-winning wide receiver for the Dallas Cowboys. His speed was so phenomenal it forced defenses to move away from man-to-man coverage that was the norm in that era.
Nehemiah was the world's best hurdler for a time in the late 1970s and early '80s, becoming the first athlete to run the 110-meter high hurdles under 13 seconds. Nehemiah was considered a favorite in the 1980 Moscow Olympics in the event but could not compete because of the U.S. boycott amid tensions with the Soviet Union.
Nehemiah played three seasons as a wide receiver for the San Francisco 49ers and was on the team that won the Super Bowl after the 1984 season. It was his last season with the team. The 49ers drafted Jerry Rice the following season.
