It's a real interesting part of the mid-eighties Mets story — Hernandez and Carter, the two captains of similar drive but otherwise very different temperaments and values, each had an older brother who preceded them into the professional life. But whereas Keith's brother accepted his career plateauing as Keith's rose toward the MLB ranks, Carter's brother resented it. And (I think) both of their memoirs of the time recount Carter being openly envious of Hernandez. You can see where Carter's personality was such that it would be easy for a family member to resent his success, but Keith seems like he was jerky enough in his own way, and yet Gary (Hernandez) always seemed to be happy and supportive to see his brother break through in the path he started. Those type of brotherly relationships appear a lot in biography and literature. It didn't particularly work out that way with my brother and myself, but stories like that sure fascinate me.
