Often referred to as a sixth tool, makeup, or intangibles can take a prospect and make the gamble on him a little more comfortable, but they don't make a prospect.  I'm surprised that I got the questions I did on this subject; maybe its sort of the buzzword of the times, I don't know.  But either way, Let's take a look at the qualities that would constitute good "makeup".

As ALWAYS, and with everything that has to do with the grading of and the evaluation of prospects, even here not everyone is going to agree on everything.  There are things that are obvious, for example:

Left handedness- there are less of these lucky people
Genetics- Did mom play college tennis or run track?  Was dad a quarterback?  Do the math
Lineage in regard to MLB bloodlines- There's just something about being able to talk to your dad about the struggles you WILL have that makes a difference

But, I've heard the same kid described by different scouts in the following pro/ negative in regard to the exact same instance:

Nice, great kid/ not very competitive
Thankful and respectful/ must be putting on an act
Super competitive/ a head case
Tunnel visioned, focused/ not a good teammate
Happy, loves to play the game/ needs more focus

Different organizations value and "weigh" makeup differently.  I've talked to some evaluators who sort of take note and if deciding between to pretty similar prospects might nudge one based on intangibles.  I've talked to others who fall so in love with intangibles that they are convinced its precisely because of them that their guy will make it through the war.

I'm glad for the discussion; I think at the very least having makeup in mind can help us raise better people, and if we're smart, better players.  Paying attention to why for instance, Derek Jeter is DEREK JETER can be a lesson in parenting on its own.  

Noticing if we have to ask our kids to work or if they can't stop working until they've nailed something gives us as parents a huge understanding of the level of innate desire our son has, and of where his standards for himself are.  Do our kids say things like, "Well, everyone else did badly today too", or do they hold themselves to their own standards?  Do they talk in the dugout the whole game and try to get the kid watching pitchers to loosen up? Who is their favorite player and why?  Do they work on what they excel at or do they work on the thing that is hardest for them?  Are they open to suggestions that they need to work more or smarter? Are they into bragging about themselves or do they try to deflect the spotlight on to a teammate? Are you given a cold shoulder after a bad game but expected to provide everything he needs for his next game? How do they respond to criticism? How do they treat the worst player on the team?  The best?

I'm not even trying to write some sort of parenting blog where I attempt at all to raise your boys.  But, by thinking about these and a thousand more questions, and then sort of matching the answers up OBJECTIVELY- as if you are evaluating another player, not yours- you can get an idea of where your son is on the makeup scale.  

As I said at the beginning, this tool, if it is a sixth tool, won't make your son a prospect, but it can make him a better bet if he is a prospect.  And if nothing else, if you parent toward nailing this one down, you will have a better son for the effort.
