I say win-win trade. I think the Lions clearly win, getting Goff and 1st rounders, dumping off their aging franchise quarterback and getting a whole slew of assets to build with. And Goff certainly isn't that much worse than Matty.
The Rams just because their MO has always seemed win now, sloughing off high picks, going for it all in FA. I still think Matty Stafford can win on a good team. Multiple veterans around the league rave about how he can sling the football.
