Pettis closed out the 2012 campaign on a roll with touchdown catches in his last two games. He caught five passes in back-to-back contests against Buffalo and Minnesota in Weeks 14 and 15. He scored the Rams' lone touchdown in a season-ending 20-13 loss in Seattle.
Pettis left Boise State holding school records in career receptions (229) and touchdowns (39).
He caught 27 passes in a 12-game rookie season that was marred by a suspension for violating the NFL's substance abuse policy. He sat out the final two games of 2011 and the first two contests in 2012.
The 6-foot-3-inch, 203-pounder is known for his skills close to the goal line. All four of his TD catches have come in the red zone.
Pettis enters this season with high expectations. After a pair of solid campaigns, he feels it is time to break out. Rams offensive coordinator Brian Schottenheimer says Pettis had a strong off-season and big things are expected from him this time around.
"I've been waiting for this moment for a while," Pettis said. "It was just a matter of time until all the things clicked and I think that's happening now. We've got a lot of weapons on this team and I think the ball is going to be spread around a lot.
I just want to be part of it."
Pettis is impressed with what he's seen from the younger wide outs. Austin and fellow West Virginia product Bailey, a third-round selection, have looked good. Bailey caught two passes for 27 yards in a 27-19 loss at Cleveland last Thursday.
"Honestly, we're a pretty confident group right now in the locker room and I don't mean that in a bad way," Pettis said. "We've put in a lot of work and a lot of time. We're just excited to go out there and show the rest of the league what we can do.
Even though we're young, we've got a lot of smart guys and a lot of talented guys."
Most of the St. Louis players were given Wednesday off. Fisher held a special-teams only practice in the afternoon. A full-squad workout, open to the public, was held Thursday.
The Rams host Green Bay on Saturday night.
