With a 1-4 current record and a couple of losses against pretty poor teams, 25th doesn't sound unfair of them to me. At least it means they think seven teams are worse than Miami. At the moment, I don't know if I could list seven teams I've got confidence in Miami beating. To be honest, I wouldn't have any faith in Miami beating Cleveland or even Arizona right now (Unless Arizona kept beating itself with stupid errors).
Sure, I'm hopeful things are going to change but currently Miami is instilling me with the same sort of confidence I had during the 2004 season.
