It wouldn't surprise me. IMO, of the Eastern teams missing the Playoffs last year, Cleveland and Detroit are the most likely to qualify this year.
I liked the Piston's draft -- Caldwell - Pope and Mitchell -- but the Free Agency signings and trades are head-scratchers. That stated, if his minutes are managed correctly, Josh Smith could be very effective if paired with Jerebko while either Monroe or Drummond are resting. I'm just not sure that playing Smith, Monroe, and Drummond together for extended minutes is a good idea.
