I would like to think that I have some quality tread left on the tires. I think the time will come, and we'll all know. I don't think there will be a question of whether I'm able to go or not able to go. That's not a desirable position for the team to accept, although it's not especially damaging if Bettis can play at least three seasons. But it's a necessary stance to take under their current constraints.
More moves are necessary and probably forthcoming.
Signing Bettis was facilitated by his desire to remain with the team and shun the free-agent market. I'm sure there are a lot of teams that would be willing to dangle the carrot out in front of you. Not to say that it would be hard to take it, but it's something I didn't want to look at. The grass is not always greener on the other side. Although they may offer you the world, what you have to give up for it means a lot.
