The real pressure point of the first round is coming in the second quarter, with picks 8 through 12 all unsigned to this point. That span includes the player who has been absent from his camp the longest thus far — defensive end Aaron Maybin has missed the Bills’ first week of practice. It also includes a wide receiver who many believed would go in the top five (Michael Crabtree of the 49ers) and the first running back selected in the draft (Knowshon Moreno of the Broncos).
