Could Mox Have Always Been Better Than Lance?
Is it possible that Mox was always a better QB than Lance, from when they were kids in pee-wee up until they got to high school? And that Lance was made starter because his father was more highly regarded than Mox's and Mox didn't live for football the way that most of the other people in town, including Lance did? Perhaps their past coaches got in Kilmer's ear about Mox having a bad attitude and not being a team player.
Also consider if you were someone as talented and athletic as Mox, why ride the bench as the back up QB, when you could play any number of other positions really well. Either as a great WR or defensive back? Possible splitting carries with Wendall. Or if Mox was QB having Lance and Wendall as the running backs.
