From the episode

he threw it too quickly to Malachi fields. It was blanketed. The next throw was an interception intended for fields. Not necessarily McCarthy's fault. That was just a miscommunication.

STACKED’s take

Negative signalUsage

Fields blanketed and miscommunicated with McCarthy due to limited reps.

Fields was blanketed on a McCarthy throw intended for him early in the game; McCarthy also threw an interception intended for Fields due to miscommunication (Fields thought he was going to sit but came through instead), showing lack of chemistry from limited reps together.
