You don't think earl Thomas shades toward Byron maxwell?You gotta look at the defenses they're playing though.
Sherm can play tight because there's always a safety on top of him.
Revis on the other hand, rarely gets Safety help since McCourty is always shading towards the opposite side.
Not saying Sherm isn't elite, but he gets more help than Revis. That Jordy catch would not have been a TD if Revis had a safety shading him.
