The Nittany Lions added their first defensive prospect to the recruiting class of 2021 with Reed's commitment.
Johnson didn't quite fully blossom into a big-time player at Penn State, but his success at Oregon could help him sneak into this year's NFL Draft.
Reid's ability to make plays at Penn State and consistently lockdown opposing receivers means he'll likely get a chance with an NFL team in this year's draft.
Hippenhammer, who opted to focus on baseball full-time this spring, is reportedly in the NCAA's transfer portal.
"We've got a bunch of other good linebackers, guys I'm really excited about. When you lose guys like Jan [Johnson] and Cam [Brown], they're tough to replace, but I like the guys in the room."
KJ Hamler's speed and explosiveness have him set up to be an early-round pick in the 2020 NFL Draft.
