And he's the rule, not the exception. So imagine the Rockies lineup if they brought in a Manny Ramirez. Who already had a 1.154 OPS while not playing a single game in Coors Field. Add a second big hitter to their lineup as well, instead of a second huge pitching contract, and the offense can put up numbers that would be hard for any team to match. Basically, I don't believe any pitcher can do that well in Colorado.
Good pitchers rely on movement and the thin air takes all movement away.
I don't think Mike Hampton or Denny Neagle is any more effective at Coors Field than a middle reliever that throws really hard. So I think the Rockies should spend their money putting together an offense that is very hard to outscore, and put together a patchwork pitching staff. Sign a David Cone and only throw him in road games. This could give Cone back his effectiveness as he needs extra rest, and give the Rockies a top pitcher on the road. They should get pitchers who throw hard to start their home games.
