There's a little bit of a false narrative I think around how their program has performed post-Beamer. They actually started regressing the last 4 years that Beamer was there, not after. Beamer went 29-23 (16-16) his last 4 seasons, never finished in the top 25. Then they actually improved during Fuente's first 2 seasons (had 2 9-win regular seasons, finished ranked) before slipping again and they've been bad ever since.
I think it is possible that the NIL era isn't beneficial for them. Beamer had good players over the years but he never consistently had elite classes and was kind of a developmental coach. There are good players in Virginia, but other schools with more resources come in and raid that state.
