I agree with those that think he is somewhat redundant with the re-signing of Helm. Riley's issue isn't a lack of skill or shot, but his heavy feet and his instance on playing sound positional hockey. He doesn't have quick feet and is slow to accelerate. Consequently, if he isn't willing to cheat his coverage he will always be too late to the play offensively (which is why he looks so unengaged). His problem this year is that he has stopped moving his feet, which exacerbates his existing problems. Quick feet allow players to recover from aggressive plays that go bad.
He will always have a job in the NHL because coaches love players like him. I could see him being included in a package with another player or being lost through the expansion draft.
