"I think last week we had some self-inflicted wounds with some penalties and we were pretty much penalty free all game," running back Steven Jackson said. "I think that was one of the huge differences between last week and this week.
"I think we have something to build off."
Lance Kendricks and Danny Amendola scored on catches of 23 and 8 yards and Jackson had 49 yards on seven carries in a 151-yard first quarter that handed the backups a two-touchdown cushion. The Rams (1-1) totaled 215 yards in a 38-3 loss last week at Indianapolis, flopping in the debut of their new coach.
"What happened tonight was directly related to what happened last week," Fisher said. "We had a really good week of practice.
"Not that we didn't practice well before the Colts game but we put some more things in and things started to fall together for us."
Bradford was 6 for 9 for 102 yards for St. Louis. Matt Cassel played the first half for Kansas City (1-1) and was 13 for 18 for 142 yards.
"Well, it was not very good tonight. And that's being a little generous to say that," Crennel said. "When you're breaking camp and doing all those kinds of things, it just shows we're not mature enough yet. No one really played good."
Kansas City committed four turnovers, including three lost fumbles, and played from behind the entire game. Last week the Chiefs beat Arizona 27-17 at home and got two touchdowns in two possessions by the first string. Wide receiver Dwayne Bowe didn't make the trip a day after signing a franchise tender.
"We've got to do a better job of protecting the football and have to be more consistent," Cassel said. "But all in all there are some positives to take away.
"We scored on the two-minute drive and I think the guys responded to a little adversity early on."
The attendance was announced at 53,272, although the 66,000-seat capacity stadium appeared to be about half-filled at kickoff.
Cassel produced an 80-yard drive capped by Hillis' 1-yard run early in the second quarter on his third series. Jamaal Charles had 17 yards on three carries, and Kevin Boss had four receptions for 62 yards.
"Obviously not good enough at all," Cassel said, "and we're back in training camp mode again on Monday."
The Rams made an immediate splash. Bradford hit Amendola for a 35-yard gain off play action on the opening snap, and St. Louis needed only four plays and 1:58 to move 80 yards to take the lead on Kendricks' catch over the middle.
Rookies Isaiah Pead and Daryl Richardson scored on short runs in the third and fourth quarters for St. Louis. The Rams had a short field after Matthew Conrath intercepted Ricky Stanzi on a ball tipped by Jerome Murphy at the Chiefs 18 on the second play of the third quarter. That set up a 1-yard run by Pead, a second-round pick slated to be Jackson's backup.
