Too me the funniest part of much of this discussion is our (and I say our, because I include myself in this) reactions when we feel that a player we really like or love to follow is disparaged.
We become invested these guys and young men. Speaking for myself, I've felt this way since I was a little kid watching the games or listening on the radio, and then snagging the sports section the next day to pour over the baseball section and listed stat sheets and box scores. At one point I could tell you the active roster and the main stats for every team in the majors (stat geek!) Heck, I still do that today... although it's a lot more high tech and in real time , annnnd perhaps a little less obsessive about the numbers.
So... at least for me, I get the "over love" for certain players. It's in our baseball DNA since we were kids. These were our heroes, our idols and while most of us really don't use those words to describe them anymore (at least not in public ), the emotional response lingers.
I'll eventually get to a point... maybe.
Kepler for example. I personally think he's a fantastic athlete, and has the mental makeup and physical tools to be an exceptional baseball player. Will he ever fully realize that potential??? I honestly don't know, and in many ways (IMHO) it isn't really that important. Baseball, like life, isn't about the destination. It's about the journey, the steps and stops you take along the way.
So, if Kepler (or Cave, or any of the others don't meet great success, are "league average" or just "meh"), I'll be disappointed but ultimately ok with it. There will be other players who come along and other players to root for.
We should all relax some, and enjoy the journey.
Merry Christmas everyone !
