If Green is garbage, what exactly is Thomson? And as far as helping the running game, he had King as RB1 in his 4 starts, Green had him as RB1 in none of his.
Ok, Litton FR year

The only thing better than Green was the TD ratio. The bad thing was that Litton's freshman year was better statistically than his junior year. He didn't get better, he got worse. His record was worse, his efficiency rating was worse, his completion percentage was worse and his TD ratio fell to 25/14. There's no guarantee we would have done any better with Litton this year because he didn't show any ability to get better while here. At least we don't know if Green has upside or not, with Litton he proved he didn't.
Green threw for more yards per game this year than Litton did in any of his three. He also averaged more yards per completion than Litton ever did (because Litton always overthrew the deep ball, what you accuse Green of being bad at). Litton's efficiency rating his best year was 137. Anything under 140 just isn't good, especially for a 3 year starter.
