Pay no attention to that man behind the curtain
2 or 3 years ago that would have been a great offer. I'm not for paying him i'd tag him and give him a low ball offer like you're suggesting. If he doesn't take it let him seek a trade or play under the tag and walk the next year.
I think my offer is fair. Maybe a hair low but still fair. I certainly would not be surprised if he got a little more.
