Is San Francisco 49ers quarterback Brock Purdy nothing more than a system quarterback?
Head coach Kyle Shanahan bristled at the suggestion on Wednesday.
"That's pretty ridiculous," he told reporters. "You just got to watch the tape. I mean, he plays at a high level every time he's been out there. And he's done it in a lot of different situations versus a lot of different defenses, on the road, at home, in playoff games, when injured. You can't do all that stuff [if you're a system quarterback]. He's been out there too long. It's on tape.
