Why would we assume that Melvin would have spent $10 million on pitching wisely? Look at the absolute garbage he has brought in on free agent deals: Suppan, Looper, Gagne, Julio, Riske, etc. Meanwhile, Cameron, according to fangraphs, was worth $18 million on the field last year and is one pace to be worth about that much again this season. In my opinion, the chances of Melvin finding that kind of value in free agent pitching were close to nil. Mike Cameron is one of the best players on the Brewers and he has far outperformed his contract.
