He was selected by the Patriots in the fourth round of the 2019 draft and started a grand total of zero games for them. There were some mitigating factors such as backing up Tom Brady in his first season in the NFL.

No, ESPN does not hate the Patriots. Wait, check that for a second. Rex Ryan definitely hates the Patriots. Give him some grace on that. The man coached the Jets for six years. You have no idea what that does to the soul. Some might also add Cam Newton to the Patriot Haters Club, since he seems to have a terrible take on something going on in Foxborough every time he appears on "First Take" or its ilk.
