I'm pretty sure the Rams could have gotten compensation for Goff if they had handled it differently. There was definite interest in Goff as reported.
In an ideal world the Rams would have done what Detroit did first and offered Goff up for auction to the highest bidder first.
Someone pays a low 1st or high 2nd for him and takes his compensation on.
Then the Rams have ammo to win the Stafford auction but would have to beat out the equivalent of a very high 1st and maybe 2nd.
The Rams did OK in that they got their guy. If they auction off Goff and don't get Stafford, the options for an upgrade go drastically down.
