Good story in 538 on Iowa. Pretty much lays out the hurdles Iowa needs to overcome given its profile. This is the key paragraph:
"In all, from 2002 to 2019, 25 teams went into the NCAA Tournament ranked in the top five in adjusted offense and worse than 75th in adjusted defense.3 Though the list includes three No. 2 seeds, seven No. 3 seeds and six No. 4 seeds, only one of the 25 teams — Marquette in 2003 — reached the Final Four. Fifteen of the 25 failed to reach the tournament’s second weekend."
So 60% of the teams with a similar profile haven't made the Sweet 16. It's just hard to go deep into the tournament being bad on defense. Not impossible, but difficult.
