It was sometime after taking one of numerous hits in his relatively limited time under center on Sunday when San Francisco 49ers quarterback Colin Kaepernick approached his two-time Pro Bowl left guard, Mike Iupati.
"C'mon, Mike," Kaepernick implored. "Do better."
Iupati let loose an uneasy laugh as he recounted the tale for reporters Monday at the 49ers' facility. Because really, Iupati agreed with Kaepernick.
And the numbers agreed with everyone. Pro Football Focus gave Iupati a grade of -2.4 after he was charged with allowing a sack and a hit on Kaepernick against the San Diego Chargers. Defensive end Corey Liuget made easy work of the 49ers' offensive line in general, Iupati in particular.
Coach Jim Harbaugh was asked what specifically the 49ers could work on with the offensive line to give Kaepernick more time and thus, better looks after he was under siege by Liuget & Co.
"Just continuing to get reps, get reps at the looks that we're going to see," Harbaugh said. "In a preseason game where it's going to be a short week, that will be difficult to do. But we'll attack that."
Iupati, it should be noted, is still recovering from the broken left fibula he suffered in the NFC Championship Game. But he was not about to blame his issues Sunday on a sore leg.
So how does he address it?
"You just watch film," Iupati said. "Sometimes you lose some, you win some. It's mainly technique. But I'm not worried about it. It's something that's an easy fix.
"It's preseason, but it's football. You're going against someone else so you're competitive and you don't want to have that happen. Especially a sack or a QB hit. But you know, it's an easy fix. That's what it is."
