It would be pretty dumb of him to not treat this as an audition, and if it works, you have to think about keeping him.
There are times when a 3-3-5 stack works. It's starting to lose it's effectiveness though as more and more offenses scheme to it's weaknesses. You really have to have the right DL (nose, specifically) to make it work. Rod Brown is awesome, and is doing a great job in his role there. Then, you have to have great secondary pieces. Remember our 2017-18 defenses when Kemon Hall, Nate Brooks, Kahiri Mohammed & Eric Jenkins were all patrolling back there in Reff's 3-3-5 stack? Great defenses! It doesn't appear that's what Coach Odom would run if it were his show though...
If you take a closer look at what @BillySee58 was saying, Odom seems to work in more of a 4-2-5 formation like Coach Bennett last year. I like this defense a little more, assuming we have good, fast, thumper LBs, (Brown & Smith will do), because it allows a 4 man rush on the regular, while maintaining a strong secondary presence.
