According to ESPN, five of the nation's top defenses reside in the Big Ten-- and Ohio State has one of them.  Not discussed was the usual juggernaut Michigan State.  Instead the article included Michigan, Northwestern, Ohio State and Wisconsin.  Sportswriter Josh Moyer opined:

"Sure, statistically, the Buckeyes' defense is ranked behind Michigan, Northwestern and Wisconsin in total yards allowed -- but that number is a little misleading... I'm talking about the fact OSU's opponents have run at least 50 more offensive plays than the opponents of those other Big Ten teams. Blame that on the OSU offense or playing faster-paced teams or whatever else, but Urban Meyer's defense... is allowing a lower opponent completion percentage (47.7 percent)... while only Michigan and Iowa have allowed fewer rushing yards per carry (3.04)."

Why do you think Ohio State's defense is so successful?
