Editor's Note: Halladay In

Roy Halladay looks like the only real superstar on the trade market, and the Blue Jays will want a minor-league roster of prospects in exchange. You can stop daydreaming of trades involving McDonald, DeWitt, Elbert and Hu. It will not happen. Toronto won't even talk with the Dodgers unless they will part with Broxton, Kershaw, Billingsley, or Kemp, and as of now the Dodgers refuse to tamper with the current 25-man roster. A trade for Kershaw may seem like a temporary solution, and if the World Series can return to Los Angeles, why not do it? Only, trading for an ace is nowhere near a lock to even make it through the first round of the playoffs (see: Milwaukee and CC Sabathia). Sure, Halladay improves the chances, but Kershaw's raw potential rivals any pitcher in the majors. The Dodgers have held on to these guys, not because they were waiting for the right opportunity to trade them as if it were a high-stakes poker game, but because they want to build a team around them. Ned Colletti has other concerns than acquiring an ace, like repairing the overworked bullpen and finding a middle-of-the-rotation pitcher to solidify the fifth-starter role. While Halladay would be a nice addition, the cost is unneccesary and even harmful.
