Personally, I think FLO stays with the team for another 1-2 years for several reasons including,
1. Flo is playing very well. He's done a great job shutting down some quality pass rushers.
2. At 33 years old, that's o.k. for an OL. We're not talking about a RB here. He should be able to play at a high level for at least another 1-2 years, esp based on his high performance this year.
3. It gives the coaching staff more time to develop and evaluate D Free (who I think is Flo's likely successor).
4. JJ knows we can be good for another few years and hopefully make a few runs at the Super Bowl. The key is protecting Romo, otherwise we're DEAD if Romo goes down.
5. The OL has been the key to this team, along with Romo, IMO. We've finally got a dominant OL. I feel confident that S Jones can get a contract done to keep the OL in tact for another 1-2 years.
I think we keep Flo, worst case tender MBIII (if we don't sign him to a longer term deal), and we keep Hamlin. I'd like to think we try and keep Crayton as well. It's hard to tell with Crayton, however. Maybe the staff thinks Hurd is ready to step into his spot, and that Austin can move up and take Hurd's spot.
