Any meetings with the Dolphins will be in an attempt to build trade value, his days in Miami are over. Pouncey likely isn't going anywhere and after all this those two can't work together. Plus the rest of the locker room would probably have a hard time accepting someone who quit on them mid season. finfan54 makes a good point about the 49ers being stocked with extra picks this year, I'm fact they have 11 total. They have:
1, 2, 2, 3, 3, 4, 5, 6, 7, 7, 7
I could see Harbaugh and the 49ers wanting to bring him in not only because he played for Jim in college, but as some sort of PR stunt that their locker room is great and accepting. We might be able to get a 7th or maybe even 6th round pick from them.
