I think statistically that would be hard to argue. 2x better means he's making like 2x amount of kicks, making double the high risk kicks, etc., which he's routinely not. He's high in all of those marks, and he's more consistently been at the top than just about anybody else, but 2x isn't really supportable logically or doesn't hold up to stats.
The difference between Tucker and some of the other really good kickers is usually 2, maybe 3, kicks per year. And that includes PATs as well.
The only thing that really separates him from others is the consistency for how long he's been doing it. There's a lot of guys that kick it well for 3-4 years and then have inconsistent years or fall off. He hasn't. That's what separates him.
