"Because they didn't block anybody," three-time Super Bowl winning offensive lineman and current analyst Mark Schlereth said. "It's endemic, to play great offense, you've got to actually block people. You've got to actually control the line of scrimmage.
"In 12 years of playing, and 15 years of broadcasting, it's the worst I have ever seen an offensive line play consistently across this league. It's pathetic."
"It was awful last night," Schlereth added. "It was an exclamation point on how pathetic the San Francisco 49ers are.
"'Oh Colin Kaepernick, it's time to move on, he can't play.' Stretch Armstrong couldn't play behind that line of scrimmage right there. I don't care if you're a super hero, you're not doing anything behind the way they played last night. They should be embarrassed ... C'mon, clown. Block somebody."
