The NCAA has passed a package of sweeping changes intended to crack down hard on rule breaking schools and coaches. Under the new legislation approved by the 13-member board of directors, programs that commit the worst infractions could face postseason bans of two to four years and fines stretching into the millions of dollars. And coaches could face suspensions of up to one year for violations committed by their staffs. The board also approved measure creating new penalty guidelines and speeding up the litigation process.
