They keep coming back to that one word: structure. Those who best know Minnesota defensive tackle Ra'Shede Hageman say it's the thing he needs most to reach his prodigious potential. Which is hard to believe when you look at him. Few Big Ten football players have bodies more structurally sound than Hageman's. Most defensive tackles are boxy in build; Hageman is long and lean at 6-foot-6 and 311 pounds. Muscles bulge from his No. 99 jersey seemingly the only Gophers garment that can contain his freakish frame. He runs a 4.9 in the 40 and has a vertical leap between 36-40 inches. He led his high school basketball team to a state title and showed off his blocking skills last week at Northwestern knocking down three third-down passes to stifle drives (he also had an interception). At 7 Hageman did backflips on demand making his adoptive father wonder what a kid who had never participated in organized athletics could do on a ball field.
