"Really, every rookie is just kind of thinking a lot right now and you've got to just go out there and play fast and quit thinking."
The other draft picks have been thrown right into the mix led by versatile first-rounder Tavon Austin, who's been as quick as advertised.
The Rams also had a special teams practice in pads on Sunday in the buildup for a scrimmage on Saturday at the Edward Jones Dome.

"By Saturday, I think they'll feel very comfortable."
