My thinking now and will only be proven if he is traded and signed elsewhere, is that he DOESN'T want to be a Raven and wants off the team. If so, he'll take a reasonable contract elsewhere, but is making these claims only because of those intentions. If he has made those counter offers, he's forcing the Raven's hand. EDC will gladly take draft capital, in a lean picks year.
Pure speculation since NO ONE really knows.
I feel like if the other top tier QBs (Hurts/Burrow) sign less guaranteed contracts then maybe that makes Lamar come down, IF he wants to stay.
At this point, Lamar can go. He's gone from "Winning a Super Bowl" to "Show me the money".
