Tony Sparano's career in Miami only boasts one success, which is the 11-5 season. Much of what Sparano has done since has been a complete disaster. Luckily for Sparano, he can share the blame with his partner in crime, Jeff Ireland.
I could mention Bill Parcells here, but since he is no longer with the organization he cannot help the team 'Go for Broke.'
There are a ton of ways that Sparano and Ireland have steered the team in the wrong direction, but the most bothersome has to be the signing of Dallas Cowboys castoffs. Ireland and Sparano have limited their free-agent signings almost exclusively to players they dealt with in Dallas.
Who is the best player of the 15-plus ex-Cowboys they have signed? Anthony Fasano, a mediocre tight end. Their justification of these signings is that the players know the system that they run, but how hard is it to coach a player into a new system? If a player can't adjust to a new system or a coach cannot help them into the new system, neither person deserves to be a part of the NFL.
It would be a different story if Miami picked up scraps like the New England Patriots do (can I get a Wes Welker or A.J. Edds anyone?). Their lack of success in free agency combined with the 0-4 record should lead owner Stephen Ross to make some changes.
