No, with all due respect your analysis isn't right as a matter of logic. Yes, college sports is different than pro sports because of the wild variances in the strength of the opponents you play. That is why we need rankings (like RPI, although I know that is flawed) that take your win -- loss record and adjust it to reflect who you played and where (or, if you prefer, your strength of schedule). I'm all for results based metrics. And ranking college teams that way makes it equivalent to just using major leagues records. But you want to adjust not for strength of schedule but margin of victory, which is an entirely different kettle of fish. So I repeat -- why doesn't MLB declare a team that goes 95-67, and is plus 200 runs for the year, a pennant winner over a team that goes 100-62 but is only plus 40 runs?
So I'll repeat my question, phrased differently so you don't take a wrong turn. Why don't pro sports not just base standings on wins and losses, but also consider margins of victory?
