A heavy drinker, McLean became better known for his erratic behavior and violent outbursts rather than his playing. In 1915, he was suspended for failing to stay in shape. He decided to let out his frustrations violently, targeting scout Dick Kinsella and Giants manager John McGraw. McLean and a group of friends attacked them in the lobby of the team’s hotel. The brawl ended when Kinsella broke a chair over McLean’s head. Unsurprisingly, McLean was immediately fired from the New York Giants and never played in another major league game.
