David DeCastro, OL, Stanford -- DeCastro closely resembles Steve Hutchinson on the field with his aggressive nature and dominant strength. Scouts wonder if DeCastro can make the move from guard to right tackle in the NFL. He's listed at 6-foot-5 on the Stanford website, the perfect height for a right tackle prospect. If his Combine measurement is close to that number and DeCastro turns in a good workout, franchises around the league could place him on their draft board at the right tackle position. His draft stock would then soar.
