There are a slew of real-life factors that contribute to the powerhouses being OP and the bad programs being bad in comparison that can't be duplicated on a video game, and that type of wild variance is not the way to go about it for a myriad of reasons but mainly because pretty much every FBS recruit begins his career in the 247 star system.
Now, recruit rankings are not gospel, but they are the "great equalizer" if you will that allows us to make comparisons between the guys that end up at Alabama and the guys that end up at Rutgers.
Speaking of your Scarlet Knights, I see that they recently got a commit from a 4 star player out of Kentucky. To have 4 stars means that he had a significant number of offers from some really solid programs, and therefore must be a quality player. But under your idea, we should essentially penalize him for choosing Rutgers and make him a 60 overall. Doesn't make sense.
We do our best to make things as realistic as possible, and it would be great if everything played out the way it does in real life. But at the end of the day, it's a video game.
While 13 certainly has some things that put it ahead of 14, blaming the ratings doesn't make sense as those can be changed in-game, and, if you're referring to the default ratings, are likely unchanged from one year to the next.
