I would like to start a discussion about bloodlines.  How important are they?  Do they affect your decisions/evaluations of prospects and players?  Is there any correlation between performance, or scouting reports, among different types?

The Boone family, Upton brothers, Young brothers, Bundy brothers, the Dwight Smiths, the Tony Gwynns, the Eric Youngs, the Maddux brothers, etc. etc.

Do family traits (athleticism, discipline, mental attitude, ultimate success) convey?  What makes one succeed and another fail?  

Both Uptons have been disciplined for lack of effort at least once for example.  Does that relate to values?

How does Bobby Bundy's breakout relate to Dylan's possible selection by the O's?

And on and on...Personally, having bloodlines makes me (even if I might not notice it) give a boost to a prospect's stock.  Is that justified?  Maybe, maybe not.  What are your thoughts?
