You're out of your mind.
As I wrote, there was no one in that period except for Dak Prescott who the Patriots could have drafted who would have been better than Garoppolo (a guy who actually was the starting QB for a Super Bowl team). No one. Not one single QB.
You actually blame Belichick for not drafting Jackson? After the Kraft freakout!?!??! That's on Kraft.
By 2019, Kraft had already read Belichick the riot act and considered replacing Brady a fireable offense. In that year, the Patriots actually traded multiple picks for WRs to appease Brady. A 1st, a 2nd, a 4th, and expended a lot of resources by bringing in free agents as well.
Not to mention the thing you WILL NEVER ADDRESS. Brady while still under contract with the Patriots made illegal maneuvers to join the archrival Dolphins.
Let's face facts about what this is really about: Brady showed his hand in the Dynasty when he got really upset at the treatment of Guerrero! That is what broke up the Patriots and Brady -- it was how Guerrero was treated.
