I prefer to use my eyes and look at the actual stats and game film than trust what people say who follow PSU football - especially those that are now making excuses for losing their coach. PSU has been in program rebuild mode since their day of reckoning. Player development happened at PSU and we know CTB can recruit.
PSU
2019 - defense gave up 14.1 PPG
2018 - 20 PPG
2017 - 15.5 PPG
2016 - 23.4 PPG
For perspective, under Jeremy
2019 - 21.7 PPG
2018 - 27.9 PPG
Left out this past COVID year. So let's assume CTB has to overcome the B10 having less dynamic O's as a rule as well as being the co-DC there. Let's exclude the impact of CJH's fast break O since we have no comparable data to review. Does anybody doubt that CTB can do at least as good as Jeremy when we know he has Garner as his DL coach? If he can develop a D that can hold teams under 30 and CJH's O clicks - the wins will happen.
Even if this future staff does not do as well as they hope, the program will be in much better shape than it has for the past 15 years.
