Certainly doesn’t preclude it, but I haven’t heard anything about DeBrisk specifically.
What I’ve been told suggests that Fitz will def be poking around the Fs and is likely to add one, but not at the top end.
I’ve heard rumblings around Mantha, but that seems less likely now IMO after adding Cotter.
Note that this was before Stamkos going free became more certain.
That’s why it remains a long shot.
