Ty Detmer had more than 200 more attempts his Heisman year than Zach had this year. McMahon had well over 100 more attempts on both of his last two seasons. Bosco 120 more attempts his junior year and 175 more attempts his senior year.
In context, Zach would’ve thrown for 6,182 yards if he had the same number of attempts as Detmer his heisman year, which would be an NCAA record by more than 300 yards. 1,000 more yards than Detmer.
