John Hall (a) / Johnny Hall

Detroit acquired Bob Keene from Arizona/St. Louis Cardinals for John Hall (a) / Johnny Hall. The available record does not show enough durable separation between Detroit's realized return and the other team's return to justify a directional win.

Green Bay acquired rights to Earl Brown from Arizona/St. Louis Cardinals for rights to John Hall (a) / Johnny Hall. The available record points to a balanced exchange, administrative move, or low-leverage transaction without a clear long-term winner. Both sides receive comparable grades.
