Each week during the college basketball season, ESPN Insiders Jay Bilas and Jeff Goodman will weigh in on the biggest questions of the sport.
The discussion: Which top-10 team has the biggest Achilles' heel?
Jay Bilas: Creighton is the best and most efficient offensive team in the country, but ranks only 88th in overall defensive efficiency. The Bluejays are better defensively than they were the past two seasons, but still give up too many easy scores. Creighton lacks size in the post, but those matchups favor Creighton on the offensive end when it can stretch a defense.
