Bough would do MUCH better if he had Michigan's defense to get him the ball with Field position
I think that cuts both ways. Also means Patterson had shorter fields, and I assume was out of the game earlier more often.
Well, you can cut that out of the equation by avoiding yards/game in the stats. Whether it's shorter fields or whether it's scheme, Blough had WAY more attempts, completions, and yards than Patterson.
That's why I didn't rely on total yards. I was pointing out that Blough had a rating just barely behind Patterson, and completion percentage and yards/att higher than Patterson. It's essentially like in basketball, using pace-adjusted stats rather than raw.
Blough was second in the league in completion percentage, second in yards/att, and a very close third in rating. Blough did have a slightly worse interception rate (1 int per 53.1 attempts vs Patterson's 57.8 attempts). He also a slightly lower TD/attempt rate, but then again that might be due to the point you make above where Purdue had longer fields.
For me, I voted Blough partly because I'm a homer, but also partly because I think he was critical to the team's success. The offense didn't start truly clicking until he took the starting job away from Sindelar. Given that he was not surrounded by a lot of talent, I'm not sure Purdue wins 6 games without Blough. I don't think Patterson was as important to his team.
