He went and started in Carolina, then got benched.
Then he was second string in San Francisco (behind Brock Purdy).
Then, after being a solid backup, he went to Minnesota to be the bridge QB until JJ McCarthy was ready.
Compared to Zach: third string in Denver behind freaking Jarrett Stidham.
Why would the Niners not go after Stidham? He beat out Zach. Why would the Niners try and sign a third string QB to replace their starter over the past three years? Especially when Purdy’s worst season is miles ahead of Zach’s best?
