This is an informative read:
It was Trump's undying need to get into the NFL that drove the billionaire to buy his way into the upstart league in the '80s, the author said. But the big league wasn't a fan.
"They just saw him as this scumbag huckster," Pearlman told Newsweek. "He was this New York, fast-talking, kind of con-man."
In the course of Trump's NFL pursuit, he made a fair number of enemies at the USFL and helped shuttle the league to an early grave. He convinced other USFL owners to challenge the NFL directly in the fall, and then led the charge on an anti-trust lawsuit against the football giant that netted a massive...three dollars. The USFL was dead by '85.
His goal was to have an NFL franchise. He tried buying the Baltimore Colts a couple years earlier, didn’t get them. He wanted an NFL franchise and he saw this as a way to do it. He talked all happy-happy about the USFL and spring football until he got the team. And as soon as he got the team he was angling in every way possible to move them to fall to take on the NFL, so his team, somehow, would be absorbed by the NFL.
His entire goal was to get him an NFL team. He didn’t care how he got it. It wasn’t like, “Oh, I really hope I can lead you guys to a merger.” He didn’t give a shit about the other owners. Like, at all. Did not care. No interest, whatsoever. His goal was to get in the NFL. If it took a merger, so be it. If it took the entire USFL collapsing and he gets an [NFL] team, that’s fine too.
