They saw all they needed to see. Look at his rushing totals from the first 2 games and you'll see that he's got nowhere to go. Granted, the Dolphins have a stout rush defense but the GM did the right thing. A few more lousy games and his value would have sunk. They got 2 picks in the 1st round alone and 10 overall for next year's draft. At least they don't have to tank it to get good picks, they can try different players and different schemes to see if something sticks. Call it a 14 game pre-season from here on out.
