As for the fans, I can just imagine him being the next whipping boy for the fans if he doesn't come out and hit .280/.360/whatever with 70 steals. Just like Jay Bruce is because he isn't Joey Votto or just like Adam Dunn was because he wasn't Miguel Cabrera.
Disagree. It's not about hype vs performance. It's about the type of performance. Both Dunn and Bruce (though Bruce to a far lesser extent) frustrate fans because they strike out a lot and fail to produce runs in "clutch" situations. Hamilton is, in important ways, the opposite. He creates excitement by turning nubbers into hits, singles into doubles and empty bases into stolen bases. At an elementary level, his speed appears to be effort, while a whiff from Dunn or Bruce appears to be lack of effort. Unfair, but that's what fans feel at some level, IMO. I don't see a player like Hamilton ever drawing the ire of the average fan like those guys do.
