Update from Birdy:
Still trying to secure a DT
Still discussing Engram
No Movement on Mercilus
Biggest issue the bills are finding is Cap Space. Not many teams willing to move off Cap Friendly Deals
I asked about Dalvin Tomlinson
Response: have not heard him discussed as option, not that it hasn't I just have not heard it.
This latest update tells me I think the Bills are likely not being involved in any deals, unless something breaks the log jam they are finding with Cap Space
