When was the last time we ever ended the season with 3 undefeated Power-5 teams?

Ohio State, LSU, and Clemson may have the most talented teams in their respective histories, at precisely the same time. What are the odds?

I might go out on a limb and say these three teams might all be top 10 or 15 all time in college football. Burrow, Lawrence, Fields, and when adding Hurts, this is definitely the deepest Playoff when it comes to QBs. All four of these guys might be 1st rounders.

Should be a really epic playoff, definitely the most competitive as to date.

Where do you think these three teams rank all time? And is this the deepest and most competitive playoff we've yet to see? I think so.
