"Mantle-Like"?

Chip Caray just called J.D. Drew's power "Mantle-like." I love J.D. Drew (especially right now), but I have no idea what this statement means. Especially since Mickey Mantle's career isolated power total is about 40 points higher than J.D. Drew's. And that's a big difference.

Fun fact: when Mickey Mantle was 36 (his final year, in 1968), he had a .237 batting average, but still managed to get on base about 39 percent of the time, which means a ridiculous number of walks. '68 was Mantle's worst season after his rookie year and he still managed to be 42 percent better than the average player.
