Depends if you are talking about dominance while in the Big Ten, or Career afterward. Kevin Anderson and Todd Martin had nice careers but didn't win the NCAA's in singles. Both had or have had solid pro careers... I would put Mike Leach (Michigan) in the mix, big college career and flourished in the pros till an injury....Maybe Barry Mackay (Michigan), pre open era but was a pro for many years...Blaz Rola (Ohio State) still remains to be seen in the pros, but had a great college career. Rajeev Ram (Illinois), Malavai Washington (Michigan), Mashiska Washington (Michigan State).... There are others, just depends how you want to judge it.
