I think the excitement and euphoria of the 2016 season may mask what are some serious talent and or depth issues at both linebacker and safety.
Most likely, the only incoming linebacker that is going to see time will be Dylan Rivers. I guess that it is possible that Brelin Faison-Walden could make the depth chart since he is coming in early but I tend to believe that he is going to redshirt. The question remains though as to whether he even stays at LB.
Starting linebackers: Cabinda (Sr/Sr), Bowen (Jr/Jr) and ????
Potential linebackers for the third spot: Cameron Brown (So/So), Koa Farmer (Sr/Jr), Dylan Rivers (Fr/Fr), Jake Cooper (Jr/Jr) and Brandon Smith (GS/Sr).
Second-team linebacker: Brelin Faison-Walden (Fr/Fr)
You cannot expect that Jonathan Thomas (Sr/Jr), a former running back, will be able to do anything to contribute meaningful minutes, tackles, etc. Jason Vranic is in the same boat.
If Marcus Allen (Sr/Sr in 2017) leaves, then there will be a severe talent and experience shortage at safety.
Starting safeties: Ayron Monroe (Jr/So) and Apke (Sr/Sr)
I pencil Monroe and Apke in there simply because they have the most experience.
Potential second-team safeties: Jarvis Miller (Jr/So), John Petrishen (Jr/So), Jonathan Sutherland (Fr/Fr), and Brailyn Franklin (Fr/Fr).
You can slice this any way that you want but the two positions are going to paper-thin on talent and depth in 2017. Someone mentioned Shaka Toney (So/Fr in 2017) but he has expressed a desire to play defensive end and I think that is where the staff has him slated.
The suggestion that CB T.J. Johnson (So/Fr) could be moved to safety makes sense. I could see that happening during spring practice as he is 6' 2"/180 but may even be a little bigger by August. I cannot see the value in moving John Reid (Jr/Jr) to safety and Lamont Wade (Fr/Fr) is too short (5' 9") and too inexperienced to jump in at safety.
I think teams will attack PSU deep at every opportunity this fall due to the lack of talent and experience at safety. I like Cameron Brown but I do have some worries about whether he can put on enough weight to play 40-50 snaps a game.
