But given San Diego's never ending search for improved cornerback play, it may be time for Smith to change his thinking when it comes to the secondary.
Thompson made his case in front of Smith and the rest of San Diego's scouts during Senior Bowl week in Mobile, Ala.
"It's not really a challenge, it's an opportunity," said Thompson of Senior Bowl week. "It's a job opportunity, really. It's for something I know that I want to do for a long time. I enjoy it."

Essentially, he did all the things Antonio Cromartie refuses to do.
"I go out and compete on the field," Thompson said. "When I'm on the field, I need to give the scouts something to have on film for the upcoming draft. I just want to compete and represent myself in a positive way."
Several teams, including the Chargers, met with Thompson and walked away seemingly impressed. Other teams he met with included the Redskins, Saints, Dolphins, Lions and Falcons.
"They're trying to get a background on you and really see who you are as a person," he said.
Thompson finished his college career with 250 tackles and seven picks, with five of those interceptions coming during his final two seasons. His interception numbers would have been much higher had teams not shied away from his half of the field.
That's why he craved the all-star environment of Senior Bowl week, where the action was consistently funneled his way.
He didn't disappoint.
"[The best part is] the opportunity to be [in Mobile], go through the process and compete with top athletes," he said. "There are a lot of good athletes who are not [at the Senior Bowl] and I was fortunate to get that opportunity."
All that remains is to see if he'll be given an opportunity in San Diego. If he is on the board at the bottom of the second round -- and if Cromartie is no longer in the picture, which many believe will be the case -- Thompson will tempt Smith's draft-day taste for cornerbacks.
Should the Chargers draft another corner? Talk about it in the message boards.
