“I think the use of iPads is probably the next great wave — for instruction, for advance scouting, for tendencies and how they’re utilized,” Wren said. “Right now, it’s still illegal to use them on the bench, but instead of using advance books, we’ve got all that information on our iPads.

“When you have notebook after notebook on every team, it’s a lot. You carry one little iPadthat’s three-eighths of an inch thick, you’ve got all of that, and more.”
