My guess is that they all stay red-shirted as I'm sure part of this is to make a push for the National Championship in 2021 with the likes of Kurt McHenry and Cam Amine hitting the lineup after their RS freshman years and Lewan and Silva being sophomores, which is probably there best shot at a team title. Their lineup in 2021 could look like this:
125 - McHenry
133 - Micic
141 - Storr or Silva
149 - Storr or Silva
157 - Lewan or Cam Amine
165 - Massa or Cam Amine
174 - Amine
184 - Embree
197 - Garcia (2020 recruit #25 overall)
HWT - Parris
I'm guessing this lineup would have sure fire AA's and potential finalists in Micic, Amine and Parris. Likely AA's in Storr, Silva, lewan and Massa. Outside shot at AA status with McHenry and Embree.
