In fact, many players signed with NFL teams for training camp and preseason action.
One of the biggest to make a splash was USFL MVP KaVontae Turpin, who sparked his Dallas Cowboys to a preseason victory over the Los Angeles Chargers by returning both a kickoff and a punt for touchdowns.
Even after NFL teams trimmed their rosters to 53 on Tuesday, the USFL is still well-represented ahead of Week 1. As of this writing, 15 USFL players have stuck with their NFL teams — including Turpin — and seven of the eight USFL franchises have at least one player on 53-man rosters.
Here's the list of USFL players who made NFL rosters:
— Ramiz Ahmed, K: Packers.
— Jeremiah Pharms Jr., DL: New England Patriots.
— Darrius Shepherd, WR: Denver Broncos.
— KaVontae Turpin, WR: Cowboys.
— Sal Cannella, TE: Packers.
— Ike Brown, CB: Raiders.
— Maurice Alexander Jr., WR: Detroit Lions.
— Darrin Paulo, OT: Lions.
