Clearly if people this dumb are getting to keyboards we need much stronger keyboard control legislation in this country.
As most college football fans would understand, UAL's Soph and two Frosh depth chart will be a JR and two Soph depth chart next year unless someone bolts. That in part fixes the "issue." As for having four, I guess the ideal is to have four and maybe even five QB prospects when you don't have one or your starter is a rising SR. Having 3 is about right if you have an established starter for next year and the year after and at least one quality backup.
