Kullman was not selected in the
1987 NFL draft. In the offseason, his secondary coach at Kutztown, Tony Leonzi, called the
Philadelphia Eagles defensive backs coach
Jeff Fisher and convinced him to give Kullman a tryout. "The coach at Kutztown contacted me during the off-season, in April, just after our first
minicamp," Fisher said. Kullman appeared in three total games for the Eagles, and was their starter in one of them. In his NFL debut, a 3–35 loss against the
Chicago Bears, he intercepted a pass and returned it 13 yards. He made his first start against the
Dallas Cowboys in the following game. He played his final career game in the following week, intercepting a pass in a 10–16 overtime loss at the
Green Bay Packers. The strike ended after the game and Kullman was released by the team. In three appearances, he made two interceptions, returning them for 25 total yards, and nine tackles. ==Later life and death==
