The catch that inspired countless memes, a tweet from LeBron James and a huge spike in jersey sales was years in the making.

It turns out Odell Beckham Jr.'s spectacular touchdown grab during his team's loss to the Cowboys on Sunday night wasn't simply a random occurrence, rather it was the result of years of practice. In fact, before a game earlier this year against the Indianapolis Colts, cameras caught Beckham Jr. practicing his one-handed grabs:

Going back to his college days at LSU, Beckham had a remarkable feel for the football. In a game against Georgia he caught a kickoff with just one hand:

He pulled the same trick during a game against UAB:

In the 2014 Outback Bowl, Beckham made this spectacular one-handed catch:

Beckham said he and former LSU teammate Jarvis Landry, who is now a wide receiver for the Miami Dolphins, would compete during their college days to see who could make the most impressive one-handed snare:

"Catching the ball with one hand is something you just have to practice, because the opportunity sometimes presents itself and you want to be prepared," Beckham told ESPN New York earlier this year. "Jarvis Landry and I would do that every day in practice. We would see who could make the most ridiculous catch. He has some of the best hands I've been around, hands down."

Beckham, whose father is a former LSU running back, credited his mom, an All-American track star, with his large hands:

"I guess I've got to thank my mom for the long fingers," said Beckham, who wears a size 3XL glove. "Her hands are maybe a half-inch shorter than mine. I know I felt [the ball] it in those two fingers and I tried my best to pull it in."

Beckham's hands measured 10 inches long at the 2014 NFL combine, which were the fifth largest out of 48 receivers in attendance. But given Beckham's size (5-foot-11), that's even more impressive. Beckham's mitts are larger than those of 6-foot-4 Buccaneers wide receiver Mike Evans (9 and 5/8 inches).

After his two-touchdown performance against the Cowboys, Beckham now has five scores through seven games. He's caught 41 passes for 609 yards and an average of 15 yards-per-reception.
