August 17, 1928 - The Detroit Wolverines NFL franchise is launched on this date. The Wolverines were a continuation of the 1926 Cleveland Bulldogs team that had fallen on hard times, but they had the NFL's second biggest star in Benny Friedman. Mr. Friedman was Cleveland native who played college ball at Michigan. Back in that era of the pigskin, college football was king and both of these mentioned pro teams attempted to cash in on the college popularity.
The team only played one season as the Detroit Wolverines, as in 1929 they were absorbed into the New York Football Giants. In an interesting spin, the Giants had never beaten Benny Friedman. They were 0-2-2 against him lifetime 0-1-1 against both the Cleveland Bulldogs and the Detroit Wolverines. The 1927 World Champion Giants swept the entire league except for one team, the Friedman lead Bulldogs. Apparently, Giants owner, Tim Mara, had seen enough and figured if he couldn't beat Friedman he bought him and the rest of the Wolverines team.
