Alex Smith was asked Thursday morning about his controversial comments this spring regarding Cam Newton. The 49ers quarterback had referenced the rookie's gaudy numbers not meshing with Carolina's 6-10 record. On Thursday, Smith reiterated his belief there is no correlation between passing yards and victories, although he did note that "obviously I got carried away there" by citing Newton's Panthers as an example. "I was going after more of the passing-yards statistic and I don't really believe there's a great correlation to winning in the NFL," Smith added. "I don't. I don't buy it. If you're looking for a statistic that has a better correlation to winning, it's probably yards-per-attempt."
