I think this couldn't be farther from the truth. Davis was brought in to replace Evans (who left and, to my understanding, wanted out of the coaching world altogether), and Eustice was brought in to replace Neff (who left for a job at Bucknell).
As Scubb said, 3-1 vs Army goes along ways. Additionally, they just had an All-American (first one since 2016), had another reach the bloodround (who returns), three more reach the round of 16 (one of which returns), and a T26 team finish (tied with Pitt, Indiana, and Lock Haven). They also had dual meet wins over Illinois & Pitt. I'd say for a service academy, this is a very successful season. Combine this with the athletes that transferred out/decommitted (Santaniello, Tallmadge, Rogotzke), I'd say the man is doing a pretty damn good job.
