One of the most important parts of the Patriots offense that needed to be upgraded this offseason was the receiving corps, and fortunately, Mike Vrabel knew that. They had the cap space to get the kind of player they needed and some intriguing options, but missed out on nearly all of them.
Instead, they took a risk by signing Stefon Diggs, who was coming off a one-year stint with the Texans, which was cut short when he suffered a season-ending ACL injury mid-season. That led to him still being available weeks after free agency began, with the Patriots being lucky enough to get him under contract.
