Hosmer was a 3rd overall pick, last year he had a so so year (and so did Moustakas). Both explode this year, it's normal because they have lots of talent that warranted high draft positions. It took a year or two for them to adjust, for some other guys, it takes more time (i.e Desmond). With high schoolers, you gotta show patience, these young kids haven't played with wood bat for 4 years at college. Look at the raw power of Burgess, you won't find much kids with his power but he has several weakneses that will take him time to improve on. Technically, if Marrero went college route, he would be a senior that would have been picked this year. He is already at AA that might play AAA next year, if he has a good season next year he might play some games in September next year ( he will be only 23 ).
It still remains that his bat projects to a backup catcher on the MLB level right now. He's got to make a very big jump at the AA level before he should even be in the conversation for 1B.
Average age is an okay thing to look at but a team like Potomac has a group of 9 guys who are already 25+, several of whom have been demoted, and 2 more about to hit that age level. That definitely skews the average age number pretty severely. It would be nice to find median/mean numbers at each level as I'm pretty sure it would chop those "average" numbers way down.
