The above link is in Swedish but a Google page translator can work some wonders. Using that tool, here's what Sodertalje sports director Per Nygard says about Davis:
While, like most college players, Davis had dreams of playing in the NHL (he attended Washington Capitals prospect camp last summer) or even signing with an AHL team, it seems like his skill set is perfect for the European game, not unlike a few other MSU grads who went on to have very solid careers there (Aaron Fox and Shane Joseph, for example).
