Dimes is in good company, nominated alongside Saracens' Mark McCall, and Leicester Tigers' Richard Cockerill.
After a turbulent 2012/13 season, Steve Diamond has turned it around, with Sharks now guaranteed top-flight European rugby next year. Now guaranteed to finish in at least 6th place, the team is a long way away from where they were last season.
Captain Dan Braid's performances have been monumental throughout the season, and his leadership has been second to none on the field.
Steve Diamond said of his nomination: "I am delighted to be short listed for the award. We've been able to compete with the top teams in the league this year, and reached our first European quarterfinal for the first time since 2008. We're now looking to finish the season strongly and have a break before we start planning for next season"
