It’s old home week for these Bills at the Coliseum

The Rams share the Coliseum with the USC football team, but it’s the Buffalo Bills who might be described as Trojans East.

Four members of the Bills played for USC — receiver Robert Woods, running back Reggie Bush, and cornerbacks Nickell Robey-Coleman and Kevon Seymour — as did defensive coordinator Dennis Thurman and defensive backs coach Tim McDonald, the father of Rams safety T.J. McDonald.

Because of an injury to Sammy Watkins, Woods has stepped into the role of No. 1 receiver and leads the team with 18 catches for 170 yards.

“I’ve been preparing for this day since I got here,” said Woods, who is USC’s all-time receptions leader. “It’s an opportunity you’ve just got to capitalize on.”

Robey-Coleman has eight tackles, a fumble recovery, a pass knocked down, a tackle for loss, and a touchdown.

Seymour, a sixth-round pick last spring, has four tackles, and he’s still wide-eyed at the thought of playing on the same team as Bush.

“We’re both grown men, but I still look at him as Heisman Reggie Bush,” he said. “It’s a blessing.”

Thurman, who played cornerback and flanker on John McKay’s 1974 national championship team, has fond memories of the Coliseum.

“As a kid growing up in Santa Monica, I remember when the Rams played there, the Trojans played there, the Bruins played there,” he said. “You had three teams that all called it their home field.

“I remember my freshman year there, playing UCLA for the right to go to the Rose Bowl,” Thurman said. “I actually got into the game and got my first college interception.”

An even bigger moment came in Thurman’s rookie season as a cornerback with the Dallas Cowboys. His team lost to the Rams at the Coliseum in Week 3, but came back to the stadium for the NFC championship game and shut out the Rams, 28-0.

“I got a game ball for that game,” he said. “That’s my last memory of playing there.”
