Columbia said Williams was hampered by the injury, but "still had some big gains even with that."
As for his future, Columbia said Williams is receiving looks from Eastern Kentucky and Western Kentucky, along with several NAIA colleges in the region.
"Eastern and Western really like him," he said.
The Cards opened the season with four consecutive wins, before closing out the year by losing five of their last seven games, including a 37-7 loss to Louisville Fern Creek in the opening round of the playoffs last week.
Columbia said a lack of depth created by late-season injuries prevented the Cards from building on the first four victories.
"Our numbers were down and that hurt us depth-wise during the second half of the year," the Clark coach said. "The guys made plays, especially early in the year."
Columbia was disappointed in his team's five losses, but was "pleased overall" with the team's progress. A year ago, the Cards concluded the season with a 3-8 record in a season filled with high expectations.
"It was good to rebound from last year," he said.
Columbia returns most of his cast next season, including quarterback Andrew Dini, but will have to replace four other starters on offense, including Williams.
"Somebody will have to step up at tailback," he said.
In his first season at the varsity level, Dini threw for 872 yards and eight touchdowns.
Between now and next fall, Columbia said the Cards "still have a lot of work to do."
"We need to get bigger, faster and stronger," he said.
