backs," that align off-tackle or off-end. These "hybrid" players are typically very quick and must be adept at running, blocking (particularly cut blocking), and receiving. Because of their positioning, they can more easily facilitate the passing game in the flexbone and serve to stretch the defensive alignment laterally prior to the snap. Teams that employ this scheme tend to amass consistently high rushing averages. The name "flexbone" is somewhat controversial and usually reflects the school of thought from which the offense was born. Some practitioners, such as Air Force's famed former head coach, Fisher DeBerry, welcomed the name flexbone because the offense was seen as a modification of the traditional wishbone. Still others, such as Paul Johnson reject the moniker, preferring instead to call their systems, the "spread offense". To these practitioners, the offense is more related to spread schemes such as the run and shoot, and simply uses the triple-option as a foundation instead of a dynamic passing game. The offense was actually born in the latter school of practitioners, with its origins attributed to Paul Johnson while at Georgia Southern in the mid-80s. He brought the system briefly to Hawaiʻi in the late '80s and then returned to Georgia Southern, which won a record six Division I-AA national titles and eight conference titles while using this offense. As traditional wishbone coaches sought to make their offenses more dynamic, they began to mimic the alignments of this "spread offense" and re-dubbed it the flexbone. The name has since stuck, most likely in order to prevent confusion with other spread offenses. By the late '90s, the flexbone was adapted by all three NCAA Division I-A military academies, where it provided strong statistical results. After bringing Navy to its greatest run of success in decades, Johnson brought the offense with him to Georgia Tech, where it has achieved great success. I-option offense Also known as the "Nebraska I-offense," this offense derives its name from its extensive use of the I formation with its vertical alignment of quarterback, fullback, and running back. Though balanced attacks from the I formation have been around for decades, the I-option gained extraordinary popularity with its employment by Tom Osborne at the Nebraska Cornhuskers. Using this offense, Osborne had outstanding success from the time of its introduction in 1980 until his retirement in 1997, including three national championships. His successor, Frank Solich, continued to have success with
