Below is why he got the extension, what he has done this year has failed to live up to the standard that he had achieved the previous 6 years. The way Iowa has lost these games, double digits losses with no team defense,has been unbearable to watch, The previous 6 years we have seen some good times that you can either agree or disagree if it has earned him another season - I believe that he deserves another year. I believe that he needs to make some changes on how he is coaching defense. Weather it is just changing how he does it or if it is bringing in a defensive minded assistant something needs to change.
This is from Coach McCraffery's bio on the Iowa web page
McCaffery was named the University of Iowa’s 22nd head men’s basketball coach on March 29, 2010. The Philadelphia native has accumulated 17 upper division conference finishes in 21 seasons as a head coach. McCaffery and the Iowa Hawkeyes have finished in the first division of the Big Ten each of the last five seasons. Additionally, Iowa is one of only three schools to have posted a Big Ten record of .500 or better each of the last five years.
Since taking over the program in 2010, the Hawkeyes have vaulted back to national prominence. Iowa has appeared in a postseason tournament each of the last six seasons (3 NCAA, 3 NIT). McCaffery coached the Hawkeyes to three straight NCAA Tournament appearances (2014, 2015, 2016) -- something that has not been accomplished in 23 years -- and reached the NIT championship game in 2013 with a team that won 25 games.
McCaffery is the first head coach to lead Iowa to 18 or more victories in six straight seasons (2012-17). Overall, the Hawkeyes have amassed 126 victories the last six seasons (21 average) under McCaffery’s direction, a total that is the third most in program history over a six-year span. McCaffery’s 137 wins rank second behind Tom Davis for the most in the first seven seasons as Iowa’s head coach.
McCaffery continues to get the most of his talent, coaching seven Hawkeyes to All-Big Ten status the past six seasons. Devyn Marble (2014), Aaron White (2015), Jarrod Uthoff (2016), and Peter Jok (2017) became the first Hawkeyes to garner first-team all-conference laurels in consecutive seasons since 1945-48. McCaffery also developed Gabriel Olaseni and Nicholas Baer into the 2015 and 2017 Big Ten Sixth Man of the Year, respectively.
The past seven years, McCaffery has coached 13 Hawkeyes to professional contracts, including Devyn Marble and Aaron White, who were selected by the Orlando Magic (2014) and Washington Wizards (2015) in the NBA Draft, respectively.
McCaffery may have pulled off his best coaching job at Iowa this past season, working with one of the youngest teams in the country and nearly receiving a berth in the NCAA Tournament. Iowa tied for fifth in the Big Ten and was one of the last four out of the tournament field. Jok led the team, becoming Iowa’s fifth Big Ten scoring champion in school history, averaging 19.9 points per game. For half the season, Jok started alongside four freshmen – Iowa’s youngest starting lineup in school history. Undaunted, McCaffery and the Hawkeyes progressed as the season went on ultimately winning four games against nationally ranked teams, including No. 21 Wisconsin and No. 24 Maryland on the road.
