Facebook friend Tom challenges references to the Seattle Seahawks' Earl Thomas as being undersized for the safety position -- and he's right.
I've said Thomas looks more like a cornerback than a safety.
But in comparing Thomas' listed dimensions to those of prototypical "center fielder" NFL safeties Ed Reed and Troy Polamalu, it became evident Thomas measured up OK.
The chart shows listed heights and weights for those safeties, plus a few others familiar to NFC West fans. I left off the bigger, more powerful safeties teams use more in run support. Comparing Thomas to Adrian Wilson wouldn't make sense, for example.
