The wide receiver scored the team's only touchdown in their 12-7 defeat to the Seattle Seahawks last weekend.
The 34-year-old told the team's website: "Watching the offense in the film room, I thought [quarterback Cam Newton] made some good decisions. I thought [offensive coordinator Mike] Shula called a great game plan. It was well-balanced.
"I was running the same routes that I run, which are variations. Short route, deep route and intermediate route. I ran all three routes. The ones that I caught were either short or intermediate.
"We gave them trouble, and they were frustrated at times. We didn't get the win, but when you get feedback immediately [from] your opponent saying that we had a lot of different route combinations and it was messing them up, I'm not really sure how much more you can take away from that."
The Panthers play the Buffalo Bills this weekend.
