The reason Plummer has fallen out of the rankings is largely because of this group of wrestlers:
3. Zach Gienger-12-St. Francis
4. Clay Cosand-12-Mankato
5. Andrew Malin-12-Plainville

They all have wins over returning state placers in 321A, they all have wins over other ranked wrestlers, and all of them are previous state qualifiers. Plummer is also a state qualifier with wins over ranked wrestlers in other classes, but he doesn't have a win over a returning state placer, which is the difference that I have between him and that group.

Then right in front of Plummer you have the two returning state placers that they have their wins against:
6. Steve Yergey-Dible-12-Hoxie
7. Levi Huneke-12-Sabetha

Just like Plummer all of these wrestlers have only lost to quality opponents who are or have been ranked this season in 321A or the other classes, or in Gienger's case he has a loss to the #3 ranked wrestler in Colorado.

Plummer is currently sitting at 8th in the rankings, but I could definitely see him placing 3rd in this bracket, maybe 2nd if Grater and Atwood end up on the same side. However, because he was not able to finish the Newton Tournament or participate in the State Tournament last season I really don't have the criteria to move him above any of those wrestlers. I also don't know of any common opponents that Plummer and that group may have wrestled this season.

I hope this explains why I have the rankings like I do.
