I think Joe Nedney has been SUPER reliable for us and I have confidence he can hit from 45+ yards consistently. Unfortunately, I think he's only got a year or two left. It's hard to tell with kickers though.
Jeff Wilikins, Gary Anderson, and Joe Nedney have been our best three though. It's tough to say with Wilkins because we only had him for a little while. Anderson was very consistent, but I never had much faith in anything more than 40 yards.
