Zim pt 2: Jacks & Yotes football camp previews & T. Denny Sanford's sports legacy

The Jackrabbit and Coyote football teams both start official practices next week. Who are the players Zim is most anticipating watching, and what storylines loom the largest for both squads?   * The Minnesota Twins continue to live in the lingering limbo of "buyer or seller" as the Aug. 3 trade deadline nears... but why does Zim think they should act like a team going places?   * The Sioux Falls Canaries have ripped out of the All-Star break on a five-game heater. Why? And why should there be belief they'll be title contenders again?   * After Happy Hour spent some time on the legacy of T. Denny Sanford earlier in the week with Patrick Lalley, Zim offers his own perspective on what Sanford (specifically, his money) had done for the sports landscape in Sioux Falls and South Dakota.
