ISU's defense was built to stop spread teams. Speed was favored over size at some positions. As a result the front seven is relatively small. At times 3-4 of the front seven last year were 220 pounds or less. The defense struggled against power running teams. Teams like KSU and Iowa (UNI?) controlled the ball on long drives and built good leads. I do not expect much of a change for this fall. The front seven while it may have a bit more size, it will be younger with less experience. Expect to see a lot of fullbacks and multiple tight ends on some opposing teams next fall.
