I would be really nice if they had a preseason top 25 that was based on talent, then you would know something. (
Edit: I found the preseason top 25 ... is it there during recruit too or only preseason

)
If you go to the RPI page, you can see team prestige, which is better than nothing.
If you sort it by Prestige, you should be able to find teams that are significantly better or significantly worse than you based on that.
