Cassel has been in the Erhardt-Perkins his whole ****ing career.
Chances are he'd crash and burn even ****ing worse in a West Coast system because it requires extreme timing and accuracy even on short routes.
As we have seen many times, Cassel's short accuracy can even be dog shit. The pass might be completed but forget about YAC.
He also sucks balls throwing on the run so good luck with that in the WCO.
