The man who could properly be called the father of the Homestead Grays, his association with the ballclub had roots reaching virtually to the team's inception, and his genius made the Grays a successful franchise. Beginning as a player, he rose through the ranks, proogressing to manager, booking agent, business manager and owner of the ballclub . . . .
[I]n 1912 Posey took charge [of the Grays] and began booking enough games to permit the players to devote all their time to playing baseball.
Within the the next decade the Homestead Grays were the biggest attraction in independent baseball . . . . As more teams appeared, they patterned their operations after Posey's Grays. Posey's dynamic leadership kept the Grays near the top ot the talent pool, and under his guidance they became a team of major-league quality and a dominant dynasty in the Negro Leagues
[Until 1929] Posey split his time between playing and managing [in addition to running the team]. In 1929 he ended his career as an active player and became a bench manager until turning the team over to Vic Harris in 1937 and concentrating on the business end of the Grays . . . .
[W]hen the [American Negro League] folded [in 1930], he returned [the Grays] to independent play, picking up some more stars, including Oscar Charleston, Josh Gibson and Judy Johnson. . . .
Posey . . . had built a powerhouse by signing players from other teams, [but now] became the target for Gus Greenlee's similar tactics. Posey lost Charleston, Gibson and Johnson among other players to Greenlee's Pittsburgh Crawfords because he could not match Greenlee's salaries . . . . [With new financial backing] Posey . . . [eventually] lured Gibson back into the fold to form a dynamic power duo with Buck Leonard.
Posey continued to corral top players, keeping the Grays the class of the league [to the time of his death]
