Morales was a 30HR - 100RBI guy in KC, one of the worst ballparks for power hitters, and won a world series with KC.  I'm not a big fan of 'hitter-only' DHs, but in TO and the AL East, he'll be fine, and when all is said and done, fans may not notice too much difference between he and EE.  
Having said that, home runs are great, but home runs on their own don't win ball games.  Good pitching will always defeat power hitting.  This TO team has been to the playoffs twice and failed to advance.  Meanwhile, its teams like KC, SF, NYM, Clev, ChiCubs, which feature far less overall power, who have been successful.  It should be clear to everyone that TO needs to get more versatile.  I like EE, JB, but this team needs more speed and balance (ie Fowler) if they hope to win a WS.  There's enough right-handed power with JD, TT, RM, who are also top-notch defensively.  I'd rather replace EE, JB with options that are better at manufacturing runs and offer defensive upside.
