I'd take Tiawan Mullen from Indiana in a heartbeat, kid was a TF All-American & lead the B1G in PBU's.
Isaiah Dunn, Camryn Bynum or Elijah Molden, any of them 3 would transition perfectly in our Defense too.
Even though we're pretty stacked at DE, I would still take Hamilcar Rashed Jr just to keep us at Elite status with pass rushers & to makeup for the loss of Rousseau.
