Each week leading up to the NFL draft April 25 in Nashville, Tenn., the Houston Chronicle's John McClain and Aaron Wilson will have weekly mock drafts of the first round and the Texans' two second-round picks on Texas Sports Nation. They also will do regular podcasts discussing their selections, the lead-up to the draft and other NFL offseason developments. Here is mock draft No. 6. (Note: EDGE refers to outside linebackers in 3-4 schemes or defensive ends in 4-3 schemes.)
