Felt it was 2 rounds too early.
He hustles and he's much better in coverage than he is against the run. I think this FO, primarily the two part-time Personnel guy slash billionaires, get enamored with shiny things, and the scouts know better than to tell them they might be wrong. Liufau is always hyped up after every play celebrating and fist pumping, and he's running all over the field. I think he guesses a lot in run defense. If he guesses right, it looks great, if he guesses wrong, there's an exposed gap. Someone on Twitter made the comp, but he very much reminds me of the NFL (not college) version of Jaylon Smith, where he is just jumping and flying around, and teams are mistaking that "energy" as being disruptive.
I don't think he is better than Overshown or even Clark. If they are imagining him as an eventual Kendricks replacement at Mike, this team will continue to get manhandled in the run game.
