Hanson's got a pretty good leg, and he was kicking really well as DarrylS already pointed out. If there's one legit criticism, it's that he hasn't dropped many inside the 20. But that doesn't mean he's the worst punter in the league like a lot of haters think.
If we had a guy like Mike Scifres, maybe that changes the equation. But Hanson wouldn't be a factor in the decision to go for it.
