Grider was part of the Cajun basketball program for two seasons in 1988-89 and 1989-90 and made a huge impact in both seasons while becoming the most effective three-point shooter in school history. He earned back-to-back first-team All-American South Conference honors as a junior and senior, averaging 23.5 points as a junior and leading the American South as a senior with a 25.5 average.
In that senior year he hit 131-of-321 three-point tries, setting Cajun school records in both categories, and he also holds the school marks for three-point percentage in a season (45.7 as a junior) and in a career (43.0). Only the legendary Dwight "Bo" Lamar scored more points in a single season than Grider did as a senior, when he finished with 739 points scored. His 41 points against Pan American in 1989 still stands as a Cajundome record.
Grider still ranks second in NCAA history in three-point field goals made per game in his career, with his 4.36 made per game (253 in 58 games) trailing only Mississippi Valley's Timothy Pollard on that list. He was a two-time All-Louisiana and All-American South first-team pick and led the Cajuns to a 20-9 record under head coach Marty Fletcher as a senior, and earned his bachelor's degree in 1993.
