Assuming Card isn't terrible or regressing for some reason at practice, he needs to start next week. I'm not a 9.95er and I'm not playing favorites.
Casey is a great guy and great teammate. But he has bad pocket presence, is a slow decision maker, and has a below average arm. Sark's scheme and Xavier Worthy make his stats looks great. But watching his overall play, everything is a half second slow. His feet in the pocket are slow, he's too casual on play action when feeling pressure, he's lackadaisical when trying to execute screen passes.
Card had a messy couple of games vs. Louisiana and Arkansas, but everything he does is a twitch faster and with more urgency.
The offensive identity is more fully formed now 8 games into the season. We now know Worthy is THE man at WR, we are still loaded at RB, and know our deficiencies on OL.
There's a reason Sark awarded Card with the starting position after the offseason. Give him another chance next week. We should be playing for 2022 at this point.
