Iowa's only real issue over the past 10 years has been recruiting. Recruiting has improved. Tom deserves credit for learning and making course corrections; not everyone can do that, and Tom is a pretty stubborn cat.
Here's the tale of the tape:
Coach: Gable
NCAA tourneys: 22
NCAA pt avg: 120.9
NCAA place avg: 1.6
% NCAAs > 100 pts: 77.3%
Coach: Zalesky
NCAA tourneys: 9
NCAA pt avg: 91.3
NCAA place avg: 3.3
% NCAAs > 100 pts: 44.4%
Coach: Brands
NCAA tourneys: 14
NCAA pt avg: 93.9
NCAA place avg: 3.1
% NCAAs > 100 pts: 28.6%
Coach: Brands (MINUS FIRST SEASON)
NCAA tourneys: 13
NCAA pt avg: 96.8
NCAA place avg: 2.8
% NCAAs > 100 pts: 30.8%
Coach: Brands (FIRST 9 SEASONS ONLY)
NCAA tourneys: 9
NCAA pt avg: 92.8
NCAA place avg: 3.0
% NCAAs > 100 pts: 33.3%
Coach: Brands (SEASONS 2-10 ONLY):
NCAA tourneys: 9
NCAA pt avg: 95.4
NCAA place avg: 2.7
% NCAAs > 100 pts: 33.3%
The last 3 are included for different comparisons to Zalesky--some will say Tom's first year shouldn't count, for example, which is a valid argument. One could also say Zalesky's first year shouldn't count. Or that 2020 should somehow be included in Tom's numbers. Or any number of scenarios. You're welcome to run them, but don't form your argument first and then cherry-pick the data simply to support it.
Zalesky was fired after 5 consecutive sub-100-pt seasons. Tom had 7 consecutive sub-100-pt seasons, ending this year. The difference, in large part, is the positive momentum created by Spencer Lee's arrival. It's not dissimilar to the impact of Tom & Terry's arrival on Gable's momentum in 1988.
I'm not dissing Brands--I'm defending Zalesky. He was a good coach but not a great recruiter. Could he have learned from his mistakes and turned it around like Tom did? Who knows? It doesn't matter now.
The most important #s right now are 129 & 1, which are the points scored and place in the most recent season. Tom brought Iowa back to the top, and he deserves all the kudos due to him.
But stop kicking Zalesky. A story can have a hero without having a bad guy.
