Some things about Pujols that make him grate on people (as opposed to merely making him great), are that
- He does not suffer fools as well as other players - reporters that ask him stupid questions get curt answers;
- He sometimes has thin skin when criticized. I remember reading a few years ago about how a perceived weight problem helped keep scouts worried about him....and Pujols response was that the fears were silly, because it was "baby fat". Fair enough, but when multiple people are worried about your weight, its fair to think their concern MIGHT be legit.
- He's blunt to the point of being undiplomatic.
I also think he's very focused on his craft, and views distractions from that focus as an incovenience, albeit a neccessary one. Put that together with points 1-3 above, and you've got someone who is not going to be smooth with teh media all the time.
Anyway, that's just what I've been thinking over the last couple years as I've kind of noticed his rough patches.
