Michael Vaughn, a member of the Maryland House of Delegates whose campaign bio bogusly claimed that he had played “3 years” for the Dallas Cowboys, told me earlier this week that I “didn’t dig deep enough” into his football career.

Well, nobody can accuse Vaughn of under-digging lately. The hole he’s dug for himself gets deeper every day.

Yesterday, in his continued crusade against a Cheap Seats column that showed the bogusness of his Dallas Cowboys claim, Vaughn told the Baltimore Sun that he also had “a short run with the New Jersey Generals.”

The Generals were the flagship franchise of the USFL. That team, which was owned by Donald Trump, and the whole league went out of business after the 1985 season.

Unfortunately for Vaughn, a few obsessive fans kept a lot of data about what went on in the league’s three-year existence, including who actually played in the USFL.

And, based on what’s out there, Vaughn’s run with the Generals was as short as his playing career with the Dallas Cowboys: So short that nobody but him remembers it.

The amazing website usfl.info has a list of 127 players who wore the Generals uniform between 1983-1985. The roster is in alphabetical order, so “Michael Vaughn” should be sandwiched between an unknown, “Walter Tullis,” and a legend, “Herschel Walker.”

Get this: It ain’t there!

Of course, USFL record-keeping was never an exact science. But Vaughn has by now also claimed to have played for, first, the Dallas Cowboys, and later, the New Orleans Saints, and the NFL says he never played for either of those teams.

So, knowing that “Michael Vaughn” isn’t among the 127 folks who get credit for playing for the New Jersey Generals, Vegas is currently leaning toward: Michael Vaughn never played for the New Jersey Generals.

But, Vegas is flighty. Show us what you got, Del. Vaughn! Keep digging!

By the way: After the USFL and the New Jersey Generals went out of business, Herschel Walker went on to play for the Dallas Cowboys. No, really! You can look it up!
