Greg Roman gave insights into his thinking when watching footage of past Jacksonville Jaguars games.
Of the Jaguars 37-3 loss to the Colts in Week 4: "Woah, boy, Indianapolis throws two picks early. They can’t get out of their own way."
Of the Jaguars 35-19 loss to the Broncos in Week 6: "Denver’s struggling to move the ball for a lot of their game. The (Jags are) pulling rabbits out of the hat."
"When you turn on the film, you may have preconceived ideas as a coach," the 49ers offensive offensive coordinator Greg Roman said of San Francisco's Week 8 opponent, which remains winless at 0-7. "And then you turn on the film.
"As always, the film tells you everything.”
So, no, the 49ers are not overlooking their seemingly lesser competitors, whom they meet on Sunday at London's Wembley Stadium as part of the NFL's International Series.
Coaches and players -- and, yes, coaches are reminding players -- are aware that no team is to be taken lightly. Not even a team, like the Jaguars, that are ranked among the league's five worst squads in both total defense and offense.
“Well, anybody in the NFL is legitimate," defensive coordinator Vic Fangio said. "They’ve got really good players. They’ve got really good coaches. This is the NFL. It’s a fine line between winning and losing. And we’ve got to approach this as our eighth game in the season, just like we’ve approached the previous seven.”
Why are San Francisco's coaches so convinced that Jacksonville shouldn't be counted out?
Jim Harbaugh, for another, noted what he sees on video of recent Jags games: constant effort and marked improvement.
"Those are dangerous teams," Harbaugh said, "when you can see them getting better."
Not all players need this reminder. Take veteran defensive tackle
He knows how "dangerous" a losing team can be. He used to play for one.
"You're playing for your job, you're playing for your career when you're on a 0-fer team," Smith said. "We expect to get the best game that the can play."
