As soon as Georgia Bulldogs defensive lineman Travon Walker's name was called by NFL commissioner Roger Goodell as the first pick by the Jacksonville Jaguars in this year's NFL draft, trading card company Panini got to work creating an instant card with Walker's image.

Michigan Wolverines DE Aidan Hutchinson then walked across the stage to accept his new Detroit Lions jersey as the No. 2 pick in the draft and posed for a photographer. The picture he took, holding up the number one jersey with his last name on it, was made almost immediately available for fans to purchase as a physical card online through Panini's website and available to fans less than a month after ordering. The same is true for 30 NFL players taken in the draft at the end of April and anyone looking for the first cards associated with these specific players and their new NFL teams.

Those cards technically have the new rookies with their NFL jerseys, but they're not really true rookie cards. They're definitely not the cards that collectors will chase and try to find at nearly any cost with the players actually wearing the NFL jerseys. Those take time to produce and for Panini, it's a process that starts well before the draft begins.

Before any prospect knew where they would be drafted, let alone walk across the stage in Las Vegas, Panini's product development team was scouring college football to try to predict which players would be on the most collectible cards coming out of the draft.

"If a guy explodes on the scene, or if he's a freshman, we're watching him until he comes out [of college] and is eligible, but we pay attention to what's happening during the college football season to start to narrow those players," said Panini's vice president of marketing, Jason Howarth. "And then through the whole draft process with the Senior Bowl and the combine and then the draft, that leads into the players we deem are going to be collectible. A lot of the decisions on who we think are going to be collectible are going to be guys that we're following throughout the college football season."

The team puts together a list of 30 to 40 players they think will make an impact or become collectible once they're drafted.

Within the trading card industry, the quarterbacks and skill position players will likely hold the most value, so those positions are weighted in the process. Prior to the draft, Panini signs individual contracts with some of the prospects they believe will be sitting at the top of the draft, as it did with Hutchinson and Ohio State Buckeyes receiver Garrett Wilson.

Once the card company has its initial list, it anxiously watches the draft to see where players will be picked.
