You're the one making a pretty bold statement, how do you figure Moore outplayed Weeden and Cassel? Moore was 0-2 as the starter and neither game he started was close. He had a 4 to 6 TD to turnover ratio and completed less than 59% of his passes. He had a passer rating of 71.0. Statistically Weeden was much better than Moore.
He completed almost 73% of his passes and had just under a 93.0 passer rating and you think Moore outplayed him? Cassel and Weeden won over 30 games between them and if the Cowboys enter the 2016 season with Moore and Dak, Romo will be the only QB on the roster that's won an NFL game. How comfortable would you be with that?
