4-2-5 vs 3-4 and Stopping the Spread

Found this article and thought it was pretty interesting. Espcially since they use Aranda's defense at LSu as the poster child for the 3-4 "Tite" defense

Lays out the pros and cons of both and here si the TL;DR version

4-2-5

Pros: 2 edge rushers, can use different coverages
Cons: B gap WLB issues that are exactly why RPOS offenses take advantage of.

3-4 or what they call a "TITE" formation

Pros: gets rid of that B Gap confusion and pushed everything outside
Cons: only 1 edge rusher on passing downs and limits DL's pass rushing potential as they generally al need to be bigger.

Food for thought in our transition, but I don't remember enough about Bo's defense to break down what he does now.
