Not necessarily. Guzman sulks and goes into slumps when he doesn't get his way. like when we moved him down to 6th in the batting order and he moped around and played like crap till we moved him back to the 2nd spot.
He said he was going to get better after '06, and no one believed him. I certainly didn't. He fixed his eyes and his shoulder and now he's The Hitting Machine.
