I don't think you'll find links to anything more concrete than what you have offered yourself, but the indication does appear to be that:
1) They offered basically everybody after their first pick and up to the Cowboys the package the Cowboys took
2) They had called us about trading at some point either before or after we traded for 19. I think it's possible that they offered us less or did so after we made our move to 19, but it's also possible it happened the other way
