Couple things...
1. We do have talent on this team. They may not be coached properly and we may not have depth, but we have talent. Honestly, look at a team like the Lions who have added talent since Schwartz became HC, but they had talent before that. Or look at the 9ers with Harbaugh. They have had talent there for awhile but just could never put it together. We need somebody that can put it together.
2.I think Ross has always got it. People hate on him for trying to make the Dolphins flashy and a big deal in Florida. I can't hate him for that, he's trying to make money. But with him not making moves earlier, when he got majority control of the franchise, we were coming off of an 11-5 year, why make huge changes after that? I think Ross is a good enough guy for giving Sparano 2 more years to prove himself. And as much as I hated to admit or see it, Ross was setting up this year to be a failure in order to start fresh next year. Once he couldn't get Harbaugh, Cowher, or Gruden last year (in hindsight) it was easy to see that he wanted to get his guys in place and make the Fins his team.
