EA: Love this question. It depends on the player, but I went to S Marcus Gilchrist for the answer.
“I couldn’t tell you. I just have a certain process throughout a game week. I like to watch players and their tendencies on how they like to run certain routes,” Gilly said. “Then I like to watch certain formations and what a quarterback likes to do – whether he likes to look off and what reads they like to go to first. Then I look at two-minute and what routes they like to run and what types of routes they like to run in backed-up situations.
