Did the Cubs have enough to get Bedard AND Roberts?

There is alot of talk amongst baseball analyst this winter over what an ace pitcher is worth and whether or not the Cubs could afford one. First, baseball had the Athletics deal where Danny Haren (who was locked up at 15.5M/3YR) of Arizona where they gave up three of their top 10 prospects (Carlos Gonzalez, Brett Anderson, Aaron Cunningham as well as low level RSP Dana Eveland and borderliner Chris Carter). Then we had the Mets trading for the best one year contract pitcher in recent history in Johan Santana, who was looking for 20+ million a year in free agency. The Mets gave up an arguably low return, two players (SRP Guerra and SS/OF Gomez) with high risk/high reward and two stable SRP players in Mulvey and Humber, who profile as a back-end starters.
