There are multiple reasons draft sheets do not happen. One of them is the ability to get deals done with other GMs once you become the rat.
As to the rest, again, NO ONE came close to offering that at the draft. As such, and just my view of course, no one is offering that right now.
So we seem to agree on the likelihood of the offer sheet.
I'll take your word on the draft day offers, I have no idea what was being proposed, or even if the Rangers were really listening on 2020 picks at the time
