Rapids To Sign Argentine

Rumor is that the Rapids are on the verge of signing the Argentina Calderon. If that's the case, what does it mean? With the MLS deadline for guaranteeing a contract approaching teams will be anxious to trade a player or simply waive them, could this mean that we'll see a few more trades including one or two involving the Rapids? Will Calderon render Roberto Brown or Jovan Kirovksi as surplus? Will Clavijo be willing to trade underutilized Jacob Peterson for a first round pick in 08? Whatever the case is if the Rapids really are bringing in Calderon at near league max-salary, they will need to get ride of one of their senior roster players to make room for him.
