If we don't get a 3rd or better, Travis will be a Bill next year. I don't think that will lead to locker room problems, but if it does it will not help Henry in any way for a guy in his contract year.
I really do not think we will be able to pick up anyone in the draft as a viable backup, so keeping Henry seems like a good option as a back up. If he doesn't like it tough sh-- for him.
In some ways I think not getting rid of Henry is a good thing. I have never seen a RB who is in 100% of the offensive plays. Henry would be satisfactory to good if he had to step in and start a few games for Willis if need be. I like what I saw from Shaud last year but I'm not sure he is the back up starter we need.
That being said I still hope we can pull off a trade to get Shelton. OL is our main priority, not RB, but we need to get a 3rd for Henry or better for it to make sense trading him.
