After a strong camp, the rookie chose an opportune time to produce his best gametape of the preseason, scoring one touchdown and setting up another in Thursday's 17-14 preseason loss to the San Francisco 49ers.
In the third quarter, Williams gave the Chargers their first touchdown of the game on a 93-yard punt return. Seven plays later, he made a 29-yard catch to the 49ers' 2-yard line, which running back Curtis Brinkley followed with a score.
Williams finished with four catches for 42 yards.
"I've been waiting on this chance the whole preseason, and I finally got it," said Williams, who was undrafted out of Tulane. "I went out there, got a lot of plays, and I just made the most out of them. I did what I was supposed to do."
For the most part.
Williams' night was nearly perfect were it not for what happened on his final touch of the game.
Capping his busy third quarter, Williams caught a pass from Jonathan Crompton, turned up field and had the ball stripped from his hands. The 49ers recovered.
Three plays later, linebacker Brandon Lang's fumble recovery would give the Chargers the ball back, but it wasn't exactly the lasting impression Williams had in mind for his breakthrough night.
With wide receivers Malcom Floyd, Legedu Naanee and Buster Davis all locks to survive Saturday's 22-man cut, Williams is battling veteran Josh Reed and impressive undrafted rookie Seyi Ajirotutu for what'll likely be two remaining spots.
He admitted he wasn't sure if Thursday's game solidified his place on the team's 53-man roster.
"I did make a couple plays, but I also had the fumble," Williams said. "I hope it does a lot for me, actually. I felt like I needed a good game today just to show I can come back and am still progressing gradually. I (showed) I'm still going to get better throughout the season, and I think it's helped me."
All there's left to do now is wait.
