I don't know, and I really don't care, right now anyways at this stage. It could be that this year is all about installing their systems + changing the culture & they want to be somewhat competitive in the process. They've determined who isn't a good fit for what they want to do and moved them out, getting value for them while they can. FWIW, I would think that next year's roster will be considerably younger with their structure in place & players like Tolbert gone.
Year 1 is a wash to me anyways, I will be happy with improvement from Week 1 to Week 17.
