The Iowa Hawkeyes close out spring football drills tomorrow in Kinnick Stadium with an intrasquad game. Iowa coach Kirk Ferentz says it has been a productive spring for his team. He’d like to see the spring workouts end with a game that has a limited amount of mistakes. Ferentz says the idea is to look sharp and play a crisp game.Ferentz will try to make the scrimmage as game-like as possible.
