mThe Jacksonville Jaguars are 0-7, but don’t let that fool you. This is a powerful team with great players that flings the ball around the field and puts opposing quarterbacks in fear. Just ask the 49ers, they’ll tell you.

Jim Harbaugh

Challenges, challenges, challenges …

“Many challenges that the Jaguars pose. They’ve been in tight games and especially you look at the Broncos game, it was a two-point game at the end of the third quarter. Defensive line is outstanding. They’ve gotten hits on every quarterback they’ve played. They’ve gotten big hits on Peyton Manning, Andrew Luck, Russell Wilson, all of them. Name a team they’ve played, they’ve gotten to the quarterback. So, that’ll be a challenge for us. They’re really good off the ball up front defensively. And another big challenge is the special teams. Jaguars special teams is outstanding. And they’re a young team in many areas, one in the secondary. But, they fly around. They play with great effort. And those are dangerous teams when you can see them getting better. So, could go on but many challenges. Like every challenge, playing in a game.”

And that special teams, my goodness …

“Very good. Talked about it after each of the ball games, especially the last three, four ball games. Special teams are playing very well, coverage units in particular.”

Colin Kaepernick

Don’t let me get smashed, o-line …

“They’re a talented front. They do a lot of things well. They’re very aggressive. They play hard. They play fast. Our offensive line is going to have to be on top of things this week.”

This is either a compliment to the 2013 Jags or an insult to the 2012 Cardinals …

“I think they are over-looked. Same way the Cardinals defense was over-looked last year. They had a good defense they just couldn’t get wins. So, I think this is a similar defense where they’re a good defense they just haven’t quite put everything together.”

Greg Roman

This is a very good team (with an average margin of defeat of 20.9 points per game) …

“We’re deep into our preparations for a very good Jacksonville team that continues to improve every week. And talking about their defense a little bit, very aggressive defensive front, always hitting the quarterback. Probably have as good a four man rush as we’ve seen. Linebackers are very active and it’s very dangerous team, just ask Denver. They had them on the ropes. And we’re getting ready for a 60-minute affair.”

Still waiting for Roman to say a defensive front “isn’t all that active” …

“Babin for sure stands out, just his edge rush pass ability, his pedigree, but really the whole front. All four, they rotate guys through quite often, but all four consistently hit the quarterback and they’re very active. You can tell that they’re a high-energy defense and while they haven’t come up with many wins they’re getting better every week. And we look at them as a very, very good opponent.”

On the guy with the coolest name on the Jags: DT Sen’Derrick Marks (the Jaguar with the lamest name is, of course, Blaine Gabbert) …

“Very under the radar. He gets off the ball as good as anybody we’ve played. He is off on the count and getting consistent penetration. So, while he’s not getting the numbers, he’s setting things up for everybody else quite a bit. So, we’re very aware of him. Very good.”

Jacksonville is 29th in the league in sacks with 11, but …

“While they aren’t getting big sack numbers, they’re getting some real live shots on the quarterback. So, it’s all clean and aggressive. So, we’ve got our work cut out for us.”

Both teams wear uniforms, they both have quarterbacks and they both …

“Very similar to Seattle. I wouldn’t say exactly the same. I think they’ve definitely adapted their scheme to players. But, very similar.”

Vic Fangio

Hey, they’re averaging an impressive 15 ppg over their last three …

“Well, they’ve made a lot of improvements here in the last few weeks. I think in the first four games, they were averaging about 220 yards a game. And then their last three games they’re averaging over 360, I believe. So, the evidence is on the tape when you watch it. And then the evidence is on paper when you look at their stats. And part of that’s coincided with the return of Blackmon, too.”

Chad Henne? He’s … yeah … well, he’s better than Gabbert …

“Yes, he’s played well. I think the last few weeks they’ve moved the ball much better. And they’re a much improved offense right now when you compare them to earlier in the season.”

Fangio is a very good defensive coordinator with many strengths, but he isn’t elite when it comes to inflating terrible opponents …

“Well, anybody in the NFL is legitimate. 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.”

Maurice Jones-Drew is averaging 3.1 ypc and probably on the downside of his career, but, uh, he’s big …

“Obviously the low center of gravity with his height and his build, 220 pounds or more packed into that shorter-type body. But, runs extremely hard. Very good on contact. He’s a good cutter. He’s a tough guy to play against. He’s so different than most running backs that you see. Most running backs that are shorter are quicker and darters, and this guy, he’s big. If he was six foot, he’d be 250 pounds.”

This is nothing new — Lou Holtz was famous for treating every game against Navy like he was facing some frightening combination of the 1984 49ers and 1985 Bears. And after the Jags responded to that record-setting 28-point spread by playing well enough in Denver to make the score 14-12 at halftime, the 49ers don’t want to give Jacksonville any extra motivation.
