Collinsworth's combination of height and speed attracted the attention of college football programs throughout the
South, and he accepted an athletic scholarship from coach
Doug Dickey to attend the
University of Florida in Gainesville, Florida. Though he was recruited as a run-first quarterback for the Gators'
option offense, Collinsworth threw a 99-yard touchdown pass to
Derrick Gaffney against the
Rice Owls in his first collegiate attempt, a toss which remains tied for the longest touchdown pass in NCAA history. Florida's option attack struggled against top defenses in Collinsworth's freshman season of
1977, so Coach Dickey decided to transition his team from a run-oriented offense to a more balanced
pro set attack for
1978. Collinsworth was moved to
wide receiver, where his new position coach was former Gator quarterback
Steve Spurrier in his first year as a coach. During his career at Florida, Collinsworth caught 120 passes for 1,937 yards, and rushed for another 210. He scored 14 touchdowns receiving, two rushing, one on a kickoff return, and threw two touchdown passes. He graduated with a bachelor's degree in accounting in 1981 and was inducted into the University of Florida Student Hall of Fame the same year. He was inducted into the
University of Florida Athletic Hall of Fame as a "Gator Great" in 1991, and as part of a recognition of 100 years of Florida football in 2006,
The Gainesville Sun recognized him as the No. 12 all-time Gator player. ==Professional career==
