I watched their games.Where did you find information that says he ran a 4-2-5 defense with a classic read and react style at Eastern last year?
I'm thinking they will be multiple and play more aggressively than his squads did at Eastern.
How about you pull up YouTube, search EWU football, watch some of the game footage and tell me what defensive front you think they predominantly ran.
Hint... It was a 4-2-5. And it was read and react.
