30/30 is a high bar, but I like your moxie. Somebody, some day will make a splash as a rookie like Trout did. Actually predicting such from a specific player, no matter how good, is statistically not wise, but it'd sure be nice. 30/30 as a rookie (with at least two weeks in the minors, assuming AA is as smart as we think) is really far out there.
I can't say I actually expect it, but I will admit to being a little disappointed if he isn't better than a two WAR player this year.
