Outside of the padded stats Stafford has from historically throwing a lot when behind and playing 100 more games, Goff has been a better QB, won playoff games, and been to the super bowl. Stafford has never come up big when it mattered even in college. Not to mention he is a walking injury, multiple back/spine issues in the last 3 seasons, multiple throwing had/arm issues his whole career. Lions fleeced the Rams. Rams may have 1 PO run with Stafford before things implode.
2011 Lions had on of the best defenses in the league and Stafford couldn't win. 4 INTs in 3 games in the playoffs with below career average stats. All while he had Calvin Johnson. Like you said Dude is fun to watch, a total gamer. I wouldn't be surprised if the Rams miss the playoffs next season.
