PRO FOOTBALL / DAILY REPORT : RAIDERS : This Is a Multiple-Personality Team

In mid-August, Raider Coach Art Shell brought his team out of Oxnard wondering how good the club was.

Four months later, he still doesn’t have an answer.

Sunday, the Raiders looked like the class of the AFC West. They scored a season-high 28 points in winning, 28-7, against the Kansas City Chiefs, a club that entered the game having allowed the fewest points in the division.

But seven days earlier, the Raiders looked helpless in a 27-3 defeat to the San Diego Chargers.

Are the Raiders as bad as they looked a week ago or as good as they looked Sunday?

“We are as good as our team played (Sunday),” Shell said. “And we can play better.

“That’s the frustrating part for all of us . . . to know that we can play an excellent football game against an excellent football team. And other times, we don’t play as well. (Sunday) we showed what kind of football team we have, how we can play when we just go out and play .”

Shell is uncertain when linebacker Riki Ellison will return. Ellison injured his foot last week against the Chargers, according to Shell, but the linebacker was not included in last week’s injury report as required by the NFL. Ellison did not play against the Chiefs.

Although the Raiders decided against activating wide receiver Sam Graddy for last Sunday’s game, Shell said Graddy, who has recovered from a broken arm, might be activated for next Monday night’s game against Miami.
