The Superbowl ring thing was quite clearly a misunderstanding: It is exceedingly odd to present jewelry to someone in such a context just for them to look at (especially to the president of Russia for a national football league in the US, as if he would be awestruck). Yet presenting jewelry to heads of state (which aren't personally kept, generally, but instead are showcased in national archives), is common. So Kraft was really silly to present the ring like that, and you can't hold that against Putin.
