Dolphins apparently don't need the work
The Dolphins were done with their work week by then. And that's the point.
On a week the team had a bye, had extra days to hone and prepare and work on the things that needs to be worked on, the Dolphins practiced one time. One time! On Wednesday.
Players were off Thursday. Players were off Friday. Players were off Saturday. Players were off Sunday.
I can appreciate the need for people to get away from the stress of an NFL season and decompress and rest and recover. But four days? So much for the bye week advantage in preparing a team.
Now, it should be said that coaches didn't get four days off. They had Friday, Saturday and Sunday off. But why would a young team in need of as much practice time as possible not take two or three days off instead of four?
I could even buy that veterans didn't need to work those days -- although they also aren't exactly lighting things up with their play this year. Why didn't the team have a rookies and young vets work day Thursday?
Didn't have to be anything physically punishing. But I think Ted Ginn Jr. could use an extra day of polishing his routes, which are still not great. I think Jason Allen could use an extra day of studying on his calls at his new (again) position of safety. I think Derek Hagan could work on holding onto the ball by catching a few more passes. I think Paul Soliai could use some more tutelage on his run-stopping technique.
I think John Beck could use an extra day of throwing to receivers he's probably going to be throwing to for the next two or three years, to get comfortable with them, to get some timing and chemistry down.
Point is if the schedule offers you an extra week to get better without having to go out on Sunday and get beat up, why would the Dolphins turn that into just one day of practice?
