I'll live with Miller in the first because of his ability as a return man (which is a need) as well as a CB. Vincent Jackson in round 2 would be ideal.
But the last two picks are awful. I like Gore, but the Broncos have other needs to fill with those comp picks and RB isn't one of them. I'm not against a QB in round 3 so long as it's Jason Campbell or Adrian McPherson. Otherwise, no sale.
