I'm not one to say Ross doesn't care. We've seen him spend plenty of money to try and bring in players.
His fault though is he is a terrible manager. When he gained control of the team, Parcells was the Director of Football Operations. This was Huizenga's last big mistake as an owner because he took a guy who was a Hall of Fame Head Coach and famously said he was a chef who couldn't buy the groceries and for some reason, thought he could run his entire football operation. On field management is quite a bit different than managing the entire football operation. The choice of Jake Long over Matt Ryan when the Dolphins had the first overall draft pick is an example of his ineptitude. Football is a QB dependent league now more than anytime in history and Parcells didn't see it.
Ross supposedly doesn't get along with Parcells and Parcells leaves the organization. This is where Ross made his biggest mistake. Instead of hiring an executive with the knowledge of running an NFL franchise, he just keeps the Parcells GM (Ireland) and coach (Sparano). Then we have been in the past 12 years of a coach firing one year, GM replacement another year, and so on. He gets rid of Tannenbaum and elevates Grier who has been with the organization for 20 years of bad drafts?
Ross, do no more harm. Hire a proven football executive immediately. Let them fire Grier and Flores and bring in replacements who will lead this team to a bright future for once. You know a lot about real estate and made your billions there. Football management is just not your thing. Hire a professional. And don't make things worse by mortgaging the future of the organization by giving 3 years worth of 1st and 2nd round picks for a guy with 22 claims of sexual deviance still to be resolved.
