Pretty sure it's in his binders, somewhere...
I'm 100% sure of that. I still don't think he shares the info widely. Probably only in heavily redacted form even to his clients. Only what he chooses to, to us fans.
We can go off recent history and have a pretty good idea that whoever offers the most money wins the bid.
We get snippets, as you suggested, but it's not in the teams' collective interest to paint a clear picture. Neither if they were the high bidder and got snubbed, nor if they were second highest and "missed it by that much." None of these scenarios or a similar one is positive PR.
it's only fitting, since none of the sides doing the negotiations offers transparency to any of the others. "This offer isn't going to get it done - I am expecting a higher offer than that this afternoon - but I can present your offer to my client and see what he says. I suggest you add that extra year, though." "We have a couple of other players in mind, if your client is really firm about that additional year." Etc etc yadda yadda.
So I retain serious doubts we fans have enough information to know these things. The teams themselves may not know whether they were second or third or whatever, though they at least can compare the particulars of their own offer to what got accepted.
I was responding mostly to the utter certainty - probably that word "Period" is what pushed past my inertia and prompted me to reply.
