Your numbers are probably in the ballpark, but its hard to find a direct comparison. Kittle is probably the better tight but he
signed his current deal at 31. Kraft is much younger, so it wouldn't surprise me if we'd have to exceed the yearly average.
On the flip side, Kittle's contract has only about 43% guaranteed. I don't think we would need to hit 80%, but more than Kittle makes sense due him being younger and more likely to play the deal to completion.
