It creates recruiting imbalances. The same thing that happens in business.
Do you believe all of Amazon, IBM, etc. success is directly related to their continual brilliant decision making?
Or was it also that they caught tail wail and through their household name which increased success by heavy multiples?
Remember when people used to call making paper copies "Xeroxing?"
The network effect is very real. This is one reason why our government sometimes is forced to intervene.
Recruiting imbalances existed long before the CFP or even the BCS.
People are just miffed that the CFP is merely confirmation that some teams are simply better than others. It seems people hoped the CFP would expose a team like Alabama, when all it's done is give further confirmation that they're as good (or better) as they seemed to be. On a year-to-year basis, certain teams will always out-recruit other teams. UCF will never out-recruit Alabama. Ever. There is no conceivable system in which they can compete with Bama in recruiting. Bama could go 0-11 for 3 straight years and still out-recruit UCF.
Short of taking a kid's choice away, you're not gonna correct recruiting imbalances.
