Big league debuts can be nerve-wracking: the new guy shows up and the carnival starts. He’s got to meet dozens of new teammates and coaches. Before the game starts everyone in the media wants a piece of him, the new kid on the block is a good story. Coaches are trying to cram information down the kid’s throat, there’s a lot he needs to absorb before 7:10. He might have family and friends flying in at the last second to see his debut; he’s got to get them tickets and make sure they’re taken care of. He might try to watch some video or read scouting reports, but how much is he absorbing?
