Burrows also played against better competition than ZW, but that's not the main point.
If you have the guy who has done it for years vs the guy who did it one season, you have to lean towards the guy who has done it every season on the biggest stage. I still take ZW over Fields (and definitely over Lance or Jones), but talk of him being above Lawrence is crazy to me.
The upside for the two players is very similar, but Lawrence has a much safer floor (barring major injury or a Luck-like retirement obviously). If the ceiling is the same, you go with the guy who provides more certainty.
