Mingo/Ogletree are not very different at all from Tez

we need 4 outside LBs, it's not competition between tez and a draft pick yet, we only have tez and Galette, we need more to compete for the starting job, not just designate Tez the starter on potential and not draft players to compete and have depth.
I don't have a problem with going OLB 1st round but I question why we would go with Mingo when we have a very similar player already. Why not go after someone with a different skill set like Jones or Werner or Ansah. Or Brandon Jenkins or Trevardo Williams in the 4th.
