Calf's definitely a big part of it as is matchups. 2 weeks ago it was Thielen and the Vikings knew Peters was banged up and repeatedly tried to isolate Thielen matched up on Peters. And a banged up Peters just has no chance realistically on someone the caliber of Thielen.

The Rams clearly tried to synchronize their pass rush with their CBs this offseason. By that I mean they went after CBs who excel at being ball hawks and forcing TOs by reading route combinations which is exactly the type of thing you have more chances to do when your pass rush is getting home and forcing pressure. Right now though Talib is gone and Peters isn't close to his KC self to the point that it doesn't matter what Aaron Donald is doing it's just too easy to complete passes vs those DBs
