this is the biggest disconnect between fans and reality. players going back for their senior season generally still sign with the team that hold their rights (provided the team actually wants them) -- going to free agency is the exception (happens maybe once a year across dozens of players). i remember fans stressing over not signing Carter Gylander after his junior year a couple years ago, and sure enough, he's in the system.
given that he told reporters he opted to come back over turning pro, i think he's very much still in the system. if he doesn't come to development camp maybe there's some concern, but it's wasted energy to worry about at this point.
i'd like to see some hits from the 2nd round too, but "safe to say he's no longer a prospect" is a dramatic overreaction. i only say something because i watch a fair bit of UND and he's absolutely signable -- bottom six potential, but plays a north-south game with energy and has solid touch around the net. he's still only 21, and given the mass exodus around the rest of his roster, he has a great opportunity to be one of the team's go-to guys, potentially a captain, etc., and turn pro around this time next year at 22 years old. seems pretty reasonable to me.
