There is an assumption that a great player should never make a mistake, so when they do it is chalked up to attitude rather than fallibility. Obviously this is gross generalization and does not apply to all fans or players, but I do think it is often the case, at least until the star becomes accepted as above reproach-like Mays. Early in his career, Mays was often criticized as a hot dog.

Mantle also was perceived early on as a player who was not dedicated to the game; only later was the emphasis placed instead on his incredible courage to play through so much pain.

Actually, the best example is Hank Aaron. Through the 50s, he was often labeled a lackadaisical player with no fire in his gut. Of course, later he was so lionized that those early assessments were forgotten and when he made a mistake it was forgiven immediately. But not earlier in his career.

the casual fans tend to dog him because he never looks like he’s going all out, doesn’t dive for balls in the OF, isn’t clutch, say he only cares about his own stats, etc. etc. and prefer a utility guy like Willie Bloomquist because all he does is hustle.

The only reason Ichiro doesn’t look like he’s trying really hard is because he’s so talented that he genuinely makes the game that look that effortless. Moral of the story – casual fans are idiots.
