Detroit Lions wide receiver Calvin Johnson has insisted that he still has another big NFL season in him despite being hampered by injury last campaign.

Johnson missed out in as many as five games last season, but was still able to collect respectable statistics of 1,077 yards receiving on 71 catches.

"No doubt. What'd I miss, four, almost five games last year? Still came up with just over 1,000. So I still have some production left," said Johnson when asked if he could produce another big showing by the Detroit News.

"I feel good, man, I'm in a good place right now. I had a whole off-season to heal up.

"The biggest difference from last year is, we know the offense way better, simply because it's the second year in. I can almost say we're 100% better than last year at this time."

Johnson has remained at the Lions since he was originally drafted in 2007.
