What? If anyone has no argument it's you. Great coaches take on rebuilds all the time. Butch at Miami, Carroll at USC, Saban at Toledo, Bama, Michigan state, etc.
After finishing his playing career at WKU in 1998, Taggart stayed on as an assistant through 2006. His first year he was wide receivers coach in 1999 and served as the quarterbacks coach in 2000. In 2001, Taggart was promoted to co-offensive coordinator. In 2002, Taggart's offense set a school record for points (432), total yards (5,479), and first downs (263) in a season that ended with the 2002 NCAA Division I-AA national title. The Hilltoppers averaged 38.8 points during the playoffs.
Taggart was promoted to assistant head coach in 2003. Taggart coached quarterback Justin Haddix, who set school career records with 8,890 yards of total offense, a 57.1 completion percentage, 50 touchdowns and a 137.28 pass efficiency rating.
When Jim Harbaugh was named head coach of Stanford following the 2006 season, he hired Taggart as his running backs coach.
In 2008, Stanford finished second in the Pac-10 with 199.6 yards per game on the ground. The team's 2,395 rushing yards were the third-highest in school history and Toby Gerhart became the fifth running back in school history to eclipse 1,000 yards.
In 2009, Gerhart finished second in the country with 144.7 yards per game and earned the Doak Walker Award, given to the nation's top running back. He finished second in Heisman voting. Stanford's 2,692 rushing yards broke the school's single-season mark, set in 1949.
Taggart left Stanford after 2009 to go back to Western Kentucky, taking over as head coach after WKU's 0-12 season. Taggart went 2-10 during his first year before recording back-to-back seven-win seasons with the Hilltoppers in 2011 and 2012. The Hilltoppers' jump from a 2-6 Sun Belt record in 2010 to 7-1 in 2011 was the largest one-year turnaround in conference history.
While at WKU, Taggart coached running back Bobby Rainey, who was named Sun Belt Offensive Player of the Year in 2010 and 2011. In 2012, Antonio Andrews, Rainey's replacement, totaled 2,977 all-purpose yards.
Taggart had the top recruiting classes in the Sun Belt Conference in 2010 and 2011.
Taggart's success at WKU led to his hiring at South Florida prior to the 2013 season. At 37 years old, Taggart was, at the time, the fifth-youngest coach in the FBS when he was hired.
Taggart took over a Bulls program that went 3-9 under Skip Holtz in 2012. Like at WKU, Taggart went 2-10 during his first season before sparking a program turnaround. USF improved to 3-8 in 2014, 8-5 in 2015 and is currently 10-2 in 2016 with a spot in the Birmingham Bowl against South Carolina waiting.
Taggart runs what he calls his "Gulf Coast Offense" at USF, which set 33 program records this season, including all-time scoring, total touchdowns, total yards, rushing yards, yards per play, yards per carry and yards and points per game marks.
USF's current No. 25 ranking in the AP Poll is just the second time in school history the Bulls have finished the regular season ranked.
Like Oregon, Taggart's 2016 Bulls are renowned for their high-powered offense and slightly porous defense. USF ranked fifth in the nation this year with 43.6 points per game. On the flip side, the 31 points allowed per game ranked 88th in the nation -- the worst defensive season in Taggart's tenure at South Florida.
