There o-line isn't that great. Columbo has been a turnstile most of the season, and they don't rush for alot of yards. Marshall and bush must be kept in check. Miami just isn't a quick score offense, and don't challenge defenses down the field.
On defense other than Cameron Wake they don't get alot of pressure on the QB. Witten should have a field day on their LB's, because they have trouble covering elite TE's. Safeties and corners have improved over the weeks, but their should be opportunities for big plays. Dez will be plenty motivated to stick it to Jeff Ireland after he insinuated that his mom was a prostitute.
Miami will play hard, but is still a bad team with plenty of holes.
30-17. Dallas!!
