Goff is still only twenty-two, and it's way too early to say anything about his career.
You're forgetting the second round pick that was used to move up to the number one selection.
And Belichick signed Haynesworth, Ocho Cinco, etc. to contracts that didn't pan out. Every GM has that.
And I guess that Johnny Hekker, Rodney McLeod, E.J. Gaines, Josh Forrest, Cory Harkey, Benny Cunningham, Ethan Westbrooks, Matt Longacre, Cody Wichmann, Cory Littleton, Cody Davis, Maurice Alexander, Tyler Higbee, Pharoh Cooper, Mike Thomas, Temarrick Hemingway, Nelson Spruce, Pace Murphy, Darrell Williams, Greg Zuerlein, Bradley Marquez, etc. don't balance out La'el Collins, who would've returned to college or refused to report to us, whose agent told the Rams front office that he'd refuse to play for them if they drafted him with a seventh round pick.
Also, I'll throw in one more Snead trade: Mark Barron for a fourth and a sixth. I'd say that it was a good trade.
