With the draft, people ignore what the coaching scheme demands. For example, Marrone wanted big road graders for the O line, so a guy like Richardson fit the mold. Roman needed more athletic linemen, so they grab Miller and Richardson becomes expendable. Roman also needed a TE (several really) in the mold of clay, and they got him. In fact, as some have stated, TE was more important to roman's scheme than WR. But blame Whaley.
On D, it's been beaten to death how Rex ruined a top 5 D. Again, a coaching issue.
I'm of the mind that it would be futile to blow it up and restart, but Rex has been nothing but a blowhard. Keeping Whaley over Rex is a better option.give the job to Lynn, and keep Taylor, and start drafting QBs.
