Haha you have no explanation. I'm glad me accidentally typing an extra D doesn't allow you to elaborate. Must not have anything to say.
When comparing Rudock's weapons to Stave's, Rudock is at a huge disadvantage. With that, creates huge apples to oranges differences between the two QB's.
First of all, teams have to respect Abbrederis with a safety over the top much more often than they have to respect any of Iowa's WR's with safeties over the top.
Secondly, teams have to bring 8 into the box at a much higher frequency because of Gordon.
Thirdly, the above two advantages creates more easy passing opportunities for Stave than for Rudock. I'd say 50% more easy passing opportunities (i.e., we'll give you the 6 yard stop route or we'll give you the 5 yard pass to the TE type opportunities).
So you take all that into perspective, and then you compare the two QB's. Visually, Rudock is a better scrambler. He makes more plays with his feet. Statistically, they're very similar. Rudock completes virtually the same percentage of his passes (60.3 vs. 61.8). Rudock has virtually the same TD to INT ratio (11-7 vs. 11-6). Rudock has more passing yards than Stave too, but I wouldn't put much stalk into that as Iowa needs to pass more than Wisconsin.
The first major point of separation comes in terms of rushing yards. Rudock has more rushing yards. Rudock has rushed for 139 yards and 5 TD's. Stave has negative rushing yards and 1 rushing TD.
All of the facts above, combined with the reality that Stave has not separated himself significantly from Rudock with his inherited advantages, points to the fact that Rudock is the better quarterback. Now go get your shine box.
