Not in my opinion, as the context again is that he was playing against competition that was mostly several years older than he was. I wouldn't expect to see him in Boston as a regular until 2013 at the earliest. I think he was rushed a bit to see how he would respond.
I guess my point is.... this seems to be closer to the best case scenario, right?
I am by no means the best judge of baseball talent, but I have watched a few games of him including some minor league games and the minor league all-star game that was on MLB Network. His receiving and blocking skills were areas that seemed to be the areas that needed the most work. In the all-star game, he appeared to be stabbing at pitches (though in fairness, he was catching unfamiliar pitchers). If he ever becomes Napoli, I'd be ecstatic. I just think that his defense is still a ways away from even Napoli at this point.
Lavarnway's brief defensive exposure in the major leagues looked promising, with a good arm and competent receiving skills.
