San Francisco 49ers linebacker Aldon Smith believes that he cannot be stopped if he is on his game and is determined to return to his best form in the 2015 season.
The 25-year-old has seen his production decline over the past two seasons as off-the-field incidents and a lack of consistency on the field have blighted his career.
However, Smith is adamant that he is one of the most dominant pass-rushers in the NFL when he is at the peak of his form.
"I don't think I played to my level, and I want to do everything it takes to play consistently at my level," Smith told the club's official website.
"I know that when I'm playing consistently and I'm on my game, I can't be stopped."
Smith has recorded 154 tackles, 44 sacks and one interception in his four years in the NFL.
