Have you actually looked at leaderboards for 87 and 88? Do you like walks and OBP? Thats really what it boils down to.
Jack Clark had a slash of 286/459/597nin 1987. Are you really going to take Dawson over that?
Strawberry 284/398/583
Guerrero 338/416/539
Davis 293/399/593
Gwynn 370/447/511
Murphy 295/417/580
Dawson 287/328/568
You are overrating his season out of bias
