Valid points on all. Personally, I thought Pett came back nicely from an absolutely horrid 2012. If he can be resigned for an incentive laced contract (similar to Delmas this year) I'd love it (no more than 2 years and no more than what he's actually worth). I just think his blend of blocking and receiving will be too hard to replace in the grand scheme of things.
Hill may be getting old, and I'm a little torn on how much I'd like him back. Maybe Moore has taken enough strides to replace Hill as the #2. I guess we won't know until next year though.
Wendling is this teams ST ace. Every team has at least one guy that will never see meaningful PT unless they're decimated by injuries, and as of now, I don't see a younger guy being able to step into that role yet.
Just my opinion though. More food for thought, a better coaching staff could help solve Petts drop issues as well.
