If the Bills added Sills, it would certainly remind me of a hockey roster like move, where teams pickup late season additions for the playoff push. But, I see this as a reaction to the loss of Kumerow. Its good insurance, but the playbook obstacle along with no chemistry with JA would make him a last resort. It also says they have no confidence in Duke Williams....but, if that is true, why are they keeping him around? A lot we don't know here, and the true injury status is the most important. Lets see...Barkley started with about 2 weeks notice a couple of years ago....and that was at QB, so Sillls, after clearing COVID, might be available for first playoff game. Another possibility is that Browns COVID listing is the real deal, and he is out with the virus. Stay tuned.
