OR you could look at it this way: Rodgers won't throw it to a receiver unless he has created a large separation. Which you could say is good, because that is why he doesn't throw many interceptions . Or he is overly cautious, depending on what tale you are trying to spin.
According to Next Gen Stats Rodgers is one of the least aggressive QBs in the league. He's on par with Mahomes, Brees and Cousins for example though.
They track aggressiveness by the amount of passing attempts a quarterback makes that are into tight coverage, where there is a defender within 1 yard or less of the receiver at the time of completion or incompletion.
but we do know guys are getting open initially but aren't being immediately thrown to. the scramble drill soon follows when the o-line can't hold their blocks for 4+ seconds.
Rodgers, like every other QB in the league, has missed open receivers. We have no idea how often it happens compared to others though.
