Villanova is looking into whether assistant coach Doug Martin may have given incorrect information in his bio submitted to the university and posted online on the school's athletic department website.
Villanova coach Jay Wright told ESPN.com he was made aware of the discrepancies after he hired Martin and the university is looking into it.
According to a statement issued by Villanova when Martin was hired, he "played collegiate basketball at UW-Green Bay for coach Dick Bennett from 1991-95."
However Green Bay has no records of Martin ever playing there. He is not listed on the all-time roster, and Andrew Gavin, Green Bay's director of athletic communications, said via email, "I do not have a record of a Doug Martin playing here and looked through our stats from each of those years as well."
While on the phone with ESPN.com, Gavin checked hard copies of both regular-season and postseason media guides from the 1990-91 through 1994-95 seasons. The name Doug Martin did not appear on any rosters or in any statistics.
The Green Bay website also includes year-by-year final statistics. Martin's name is not listed as a team participant in any of the years he claims to have played there.
Martin did not return messages left from ESPN.com.
Bennett, Martin's supposed coach, said he has absolutely no recollection of Martin.
"He certainly didn't play for me," Bennett said.
Former Wisconsin-Green Bay star Jeff Nordgaard, who played for the Phoenix from 1992 to 1996, said he did not recall a Doug Martin on his team.
"I didn't play with anyone by that name," Nordgaard said. "So unless he changed his name ..."
On his Linkedin profile, Doug Martin -- confirmed to be the same Doug Martin as the one at Villanova -- lists himself as having bachelor's degrees from both Wisconsin-Green Bay and Viterbo University. He also claims he is a four-year letter winner at Green Bay as well as "captained team my senior year."
"I was team captain then," Nordgaard said.
The Linkedin profile has since been taken down.
Martin appears to have said he was a former Phoenix player for some time. On the Paul VI High School website, where Martin worked prior to Villanova, his bio says he received a bachelor's degree in sociology from Viterbo University, an NAIA school in La Crosse, Wis. The high school site also includes the same information about Martin playing at Green Bay.
But according to the Viterbo website, a Doug Martin is listed as a basketball letter winner from 1990-94. He played in 87 games in that period, scoring 222 points.
