St Louis Rams wide receiver Austin Pettis has insisted that he now feels comfortable in the league after two average seasons in the NFL.

Pettis said that the key thing has been learning how to make quick decisions, which led to his best-ever figures of eight catches and 78 yards against Atlanta Falcons in week two.

"This being my third year, I feel a lot more comfortable, getting adjusted to not just the NFL, but also the offenses and concepts and really understanding those," Pettis told the club's official website.

"It helps me to play fast, so I think just being more comfortable helps me to play fast, and the results are there."

Pettis has played 30 games for the Rams since turning pro in 2011.
