There's a Buckeye team from 2002 that would beg to differ.
While the 2002 Bucks played in quite a few close games, they never came close to blowing a big lead.
Games in which they had a 18-point lead at any point:
Texas Tech, 45-21
Kent State, 51-17
Washington State, 25-7
Indiana, 45-17
San Jose State, 50-7
Minnesota, 34-3
In the remaining games, they never had more than a 10-point lead except at Northwestern:
Cincinnati, 23-19 (biggest lead, 4 points - final)
Northwestern, 27-16 (biggest lead, 15 points - 24-9 in the third)
Wisconsin, 19-14 (biggest lead, 7 points - final)
Penn State, 13-7 (biggest lead, 6 points - final)
Purdue, 10-6 (biggest lead, 4 points - final)
Illinois, 23-16 (biggest lead, 7 points - final)
Michigan, 14-9 (biggest lead, 5 points - final)
Miani, 31-24 (biggest lead, 10 points - 17-7 in the third)
Also note that in six of those eight close games, our largest lead was the final score. So, yeah, the 2002 Buckeyes have absolute zilch to do with almost blowing 29-points leads.
