Thanksgiving week has been a whirlwind for Iowa’s Aaron Graves, and the emotion caught up with him minutes after the Hawkeyes wrapped up a 40-16 win over Nebraska. Graves’ wife, Aubrey, gave birth to their first child about 3 p.m. Thursday and five hours later the defensive lineman was on a Hawkeye booster’s private plane flying from Iowa City to Lincoln. The 6-foot-5, 295-pound senior from Dayton, Iowa, choked up and needed a minute to compose himself when asked about his son, Grayson, who weighed in at 6 pounds, 5 ounces. Mom and baby are doing well, he said.
