Depth charts in college sports already work to even out the teams. The reason a top QB recruit would go to Notre Dame instead of USC is because USC already has 3 top ranked QBs and you wouldn't get any playing time until your senior year. Whereas at a lower tier school that same recruit might be able to start much earlier and therefore be able to enter the league draft earlier. Obviously this doesn't solve the problem 100% but you already see recruits taking this into account when signing and in some cases even transferring.
