Colin Kaepernick said, in so many words, that Trent Dilfer doesn't know what he's talking about.

After the 49ers lost to Carolina Sunday, with Kaepernick passing for just 91 yards, Dilfer—the former Super Bowl-winning quarterback and current ESPN analyst —called Kaepernick's quarterbacking, specifically his reads, "remedial."

Asked what he thought of Dilfer's comments by reporters after practice Wednesday, Kaepernick replied tersely, “Well, I think you should ask him if he knows what my progression is first before he says that.”

Kaepernick said he had not heard what Dilfer had said before he was told Wednesday, but added, "He’s not in the building with us, so what he’s saying really doesn’t affect me at all. I’m worried about what this team thinks and what I’m doing in here with my teammates.”

The 49ers, 6-3 and trailing Seattle in the NFC West by two games in the loss column, play at New Orleans Sunday.

Coach Jim Harbaugh defended Kaepernick again Wednesday, for the third time since the loss Sunday. “We don’t think anything’s wrong with Colin,'' he said. "We feel like his progression’s been very good. He’s played winning football for us and that’s what we expect.”

When it was pointed out that a lot of the wrinkles that made Kaepernick so effective after becoming the starter last season were not being used this year, Harbaugh said: "Here’s the thing, you’re only as good as your last quarters of football. We understand that. It’s very, very convenient, very easy to say why not run? Why not pass? Why not move the pocket? Why didn’t you throw a screen? Why didn’t you go for it on fourth and one? ... Hindsight’s very convenient.”
