The Dolphins would save around $2.7 million on the salary cap if they cut Tony McDaniel, and I think they should do it if Kheeston Randle and/or Ryan Baker show anything.
Jared Odrick is a defensive tackle trying to play defensive end. You ask where's the depth at DT if you cut McDaniel, well there it is right there. You have Soliai, Odrick and Starks, and that's plenty. Behind them you have Randle and Baker and I believe both are roster worthy. The Dolphins have too many DTs, not enough DEs, IMO.
The thing that changes everything is the fact that salary cap space can be EASILY rolled forward now. Saving that $2.7 million means $2.7 million more in cap space in 2013 and beyond. Three years ago that wasn't the case. It wasn't very easy to roll space forward, you had to do it indirectly enlisting the help of some of your trusted veterans who would all their contracts to be re-done to include some incentives they knew damn well they were never going to be achieved. In most cases, teams were forced to allow millions in cap space to just get flushed down the toilet. Now, when you make your final cuts, you know that whatever space you have this year will be rolled forward to next year. You could see as much as $6 or $7 million of salary cap space cleared in the final cut downs, because teams will be making the choice of whether this guy is so valuable relative to the guy right below him on the depth chart this year, that it's worth $3 million or whatever of potential 2013 cap space.
Quite frankly, I don't think McDaniel is that valuable.
