We've never beat more than 3 P5 teams in a single year. Our best chance to do so was probably 2013 when we went 2-5 (Thanks to losing at Virginia).
It would be nice to build a little better record against P5 teams. This will be a tough year to do it, though; as will next year. 2020 we might have a better chance.
Here's to hoping (dreaming?) that it happens this year.
