In his one year as the OR head coach, the 41-year-old improved the Ducks from 4-8 to 7-5, ensuring their bowl eligibility this season.
This represents a rare change of pace for Florida State, which has only had two head coaches since 1976.
Odell Haggins served as the Noles' interim head coach for the regular-season finale against Louisiana-Monroe. Taggart is leaving the Ducks after just one season, where he went 7-5.
Once Jimbo Fisher's interest in Texas A&M started to gain traction, Taggart quickly became a top target for Florida State officials and their efforts to gather research on potential candidates.
"His values are in line with ours, with academics as important as the product on the field", said Ed Burr, chairman of Florida State's board of trustees.
And now he's the Seminoles' next head coach.
The Ducks are putting all their chips on Willie Taggart staying in Eugene as they've tried to lock him up long term.
Taggart then made his return to Western Kentucky in 2010 when he was hired as their head coach.
Taggart, a native of Bradenton, Florida, will be the Seminole's first full-time African-American head coach. Will he do any different with the garnet and gold? Previously, Taggart cultivated a reputation as a program-builder at Western Kentucky (where he was a quarterback in the 1990s) and South Florida.
Taggart is also known for bringing in elite recruiting classes and knows the Florida circuit as well as anyone. Florida State is 6-6 this season and will face Southern Mississippi in the December 27 Independence Bowl.
