In the 1968 NCAA University Division football season, the system of "polls and bowls" changed. The Associated Press returned to its pre-1961 system of ranking the Top 20 rather than the Top 10, and voted on the national champion after the bowl games, rather than before. During the 20th Century, the NCAA had no playoff for the college football teams that would later be described as "Division I-A". The NCAA Football Guide, however, did note an "unofficial national champion" based on the top ranked teams in the "wire service" (AP and UPI) polls. The "writers' poll" by Associated Press (AP) was the most popular, followed by the "coaches' poll" by United Press International) (UPI). In 1968, the UPI issued its final poll before the bowls, but the AP Trophy was withheld until the postseason was completed. The AP poll in 1968 consisted of the votes of as many as 49 sportswriters, though not all of them voted in every poll. With a Top 20 for the first time since the 1960 season, there were more matchups between ranked teams. Those who cast votes would give their opinion of the ten best teams. Under a point system of 20 points for first place, 19 for second, etc., the "overall" ranking was determined. In 1969, there were four regular season games that matched "Top Five" teams. ==Rule changes== * The 1967 punting rule requiring five linemen on the kicking team to remain at the line of scrimmage until the ball is punted was repealed. * Eliminating the "flex shift" (offensive linemen raising up then dropping back down into position, used by Kansas and UCLA the previous season and later popularized by the Dallas Cowboys) by requiring an offensive player to hold his position when he gets "on or near the ground". * The game clock will be stopped on all first downs to move the chains, then restarted again. * The "tackle-eligible" pass play was declared illegal by requiring five offensive lineman numbered 50-79 to be on the line of scrimmage and declaring none of them are eligible receivers. * Prohibiting the receiver of a fair catch who does not catch the ball to then become a blocker. * Limiting the legal clipping zone to a rectangular point three feet by four yards on either side of the ball. * Defensive players who intercept a pass within five yards of the end zone and his momentum takes him into the end zone, the ball will be put in play at the spot of the interception if the defensive player does not attempt to advance the ball out of the end zone. * Length of time-outs are shortened from 120 seconds to 90 seconds. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1968 college football season」の詳細全文を読む スポンサード リンク
