PRO FOOTBALL : Where Did These Rams Come From? : NFC: They have yet to commit a turnover this season and are 4-0 after beating Bears, 34-28.

What a difference a change of address has made for the Rams.

The team won four games all last season when it was based in Anaheim, and now, as the St. Louis Rams, it has won four in four weeks.

And get this--the Rams have yet to commit a turnover.

On Sunday, they defeated the Chicago Bears, 34-28, before a sellout crowd of 59,679, with only 45 no-shows.

There was some bad news for the Rams, however. Quarterback Chris Miller sustained yet another concussion in the fourth quarter when he was hit by Jim Flanigan, then leveled by Vincent Smith. He watched the last 9:42 from the bench.

“When I let go with a pass, it felt like somebody hit me with a baseball bat in the head,” Miller said. “I was kind of out for a second, and then I guess I wasn’t quite sure where I was.”

Miller said he was fine except for a “hell of a stiff neck,” and he expects to play next week at Indianapolis.

Backup quarterback Mark Rypien led the Rams to their final score, a 25-yard field goal by Steve McLaughlin with 2:42 to play against the Bears (2-2).

Miller completed 21 of 31 passes for 231 yards and three touchdowns in his best day as a Ram before sustaining the concussion. Last season, he had two concussions, and he had another in the exhibition opener at Seattle, causing him to go to a special air-filled helmet.

“It’s unfortunate for Chris,” Rypien said. “Gosh, he had a whale of a ballgame, a tremendous game. It’s unfortunate those things keep occurring.”

The Rams are 4-0 for the first time since 1989, when they reached the NFC championship game. Entering this season their record was 23-57 in the 1990s, tied for the worst in the NFL.

Rypien said you can forget about all of that.

“I felt my first game here that this was a team that had the potential to go the playoffs,” Rypien said. “Even in a rebuilding year, even in a restructuring year, even in a year when they were shipping out and going somewhere else with a new coach.”

Error-free ball has been the biggest reason for the turnaround. The Rams avoided a big problem when a leaping Todd Kinchen fumbled high into the air on a punt return with 6:42 to go, but teammate Cedric Figaro recovered.

The Rams also forced two turnovers, their 13th and 14th of the year, as they jumped out to a 10-0 lead. Toby Wright returned an Erik Kramer fumble 73 yards on the game’s second play.

“We played into their hands,” Bear Coach Dave Wannstedt said. “That’s dumb. You can’t do that on the road with a crowd like that.”
