He's had the most carries this preseason with 19, gaining 59 yards. He also has the only lost fumble by a running back.
"I've been trying to prove myself since I came here. Really, the only difference is that Steven's gone," Pead said. "I still come in, ready to work, trying to find a spot on the team whether it be special team or offense."
The Rams game at Denver last Saturday was another missed chance for the running backs to get work.
St. Louis planned to work on its running attack, only to change as the game unfolded.
Lineman Rodger Saffold, returning from a shoulder injury that limited his work leading up to the game, lasted the entire first half after it was anticipated he might only play a handful of snaps.
The Rams have also wanted to focus on their passing game and this year's top draft choice Tavon Austin and third-rounder Stedman Bailey at receiver. Fisher wants to enhance the downfield options for quarterback Sam Bradford.
He said if that part of the game develops, it can only serve to help his young running backs, that includes two second-year players and two rookies in the top four on the depth chart.
That has limited the chances for rookies Zac Stacy, a fifth-round choice from Vanderbilt, and Benny Cunningham, from Middle Tennessee State who signed as an undrafted free agent. But both should play a role in the upcoming season.
How much might be determined Thursday.
"I think you'll probably see some more," Fisher said. ""We'll get a chance to look at them this week. With Isaiah not being available to us in Week 1, we'll have to look at all the backs."
