Yes
Things change quickly in the college game. I don't want a DC that hasn't had(proven) good defenses against a modern spread. While English hasn't failed, he hasn't succeeded in the role either. He was good back when everyone was running the I.
TBH I'm worried about the same thing with Randy Shannon, although I won't hold this season against him given the credit card fraud situation and how shorthanded he was, especially with an offense that didn't exist.
We aren't in position for on-the-job training right now since we're planning to compete for titles next year. Need a plug and play top 25 level DC just like the one that left us. We were a top 20 defense last year and lose no one with a likely NFL future while adding a couple with that potential. We could easily field a top 10 D next year. Go get a sure thing.
